Subject: [PATCH 03/37] Refactor installer and uninstaller scripts

Major refactor of install.sh and uninstall.sh to improve robustness, cross-distro support, and low-RAM VPS behavior. install.sh: add safety cd, colored helpers, Python detection with fallback to 3.12, RAM check and swap setup, noninteractive apt/dnf and needrestart handling, Docker/Docker Compose/Node installation, clone/update repo, create system dirs and install bundled templates, set up venv and dependencies, generate .env, create self-signed SSL, install systemd service, configure nginx reverse proxy, build frontend on host to avoid Docker memory issues, start services, perform health checks, and send install telemetry. uninstall.sh: formatting/consistency fixes, require root, safer docker compose teardown, remove /etc/serverkit and /var/serverkit, and send uninstall telemetry. Also add CONTRIBUTORS.md and remove the .claude code-review SKILL.md.

-name: code-review
-description: Run a multi-perspective code review on recent changes using specialized reviewer personas. Each reviewer focuses on their domain — security, ops, cross-platform, API design, frontend, and performance. Produces a dated review report.
-argument-hint: "[file, directory, or git range]"
----
-
-# Code Review — Multi-Perspective Audit
-
-Review code from the perspective of 6 specialized reviewers, each with their own focus area. Produces a structured report in `.reviews/`.
-
-## Scope
-
-Determine what to review based on the argument:
-
-- **No argument**: Review all uncommitted changes (`git diff` + `git diff --cached`)
-- **A file or directory path**: Review that specific path
-- **A git range** (e.g., `main..HEAD`, `HEAD~3`): Review that commit range
-- **`last`**: Review the last commit (`HEAD~1..HEAD`)
-
-## The Reviewers
-
-### Mara — Security
-
-Focuses on authentication, authorization, and injection vectors.
-
-- JWT handling: token validation, expiry, refresh flows
-- SQL injection: raw queries, unparameterized input
-- XSS: unsanitized user input rendered in responses or frontend
-- CORS misconfigurations
-- Path traversal in file operations (`../` in user-supplied paths)
-- Secrets in code (API keys, passwords, hardcoded tokens)
-- Missing `@jwt_required()` on API routes that need auth
-- CSRF protection gaps
-
-### Raj — Ops & Infrastructure
-
-Focuses on subprocess calls, privilege escalation, and system operations.
-
-- Missing `sudo` on privileged commands (systemctl, firewall-cmd, ufw, certbot, nginx)
-- Raw `subprocess.run()` that should use `run_privileged()`, `ServiceControl`, or `PackageManager`
-- Missing error handling on subprocess calls (unchecked `returncode`, no try/except)
-- Hardcoded paths that assume specific filesystem layout
-- Logging gaps: operations that modify system state without logging what they did
-- Service restart ordering issues
-
-### Sol — Cross-Platform & Containers
-
-Focuses on portability across distros and container environments.
-
-- Distro-specific commands (`dpkg`, `apt`, `rpm`, `dnf`) without `FileNotFoundError` handling
-- Unguarded `/proc/` and `/sys/` reads that fail in LXC/containers
-- `psutil` calls that return `None` in containers (`disk_io_counters`, `sensors_temperatures`) used without null checks
-- Docker socket assumptions without availability checks
-- Firewall commands that need `CAP_NET_ADMIN` (dropped in unprivileged LXC)
-- Hardcoded `/dev/` device paths
-- Assumptions about init system (systemd vs others)
-- Package manager detection that only checks one family
-
-### Kai — API Design
-
-Focuses on REST conventions, error handling, and request/response patterns.
-
-- Inconsistent error response format (should always be `{'error': 'message'}, status_code`)
-- Missing input validation on request body fields
-- Wrong HTTP status codes (e.g., 200 on error, 404 when it should be 403)
-- Missing pagination on list endpoints
-- Endpoints that return too much data (no field filtering)
-- Inconsistent URL naming (`/api/v1/` prefix, plural nouns)
-- Missing rate limiting on sensitive endpoints (login, password reset)
-- N+1 query patterns in endpoints that return lists
-
-### Lena — Frontend
-
-Focuses on React patterns, UX quality, and style consistency.
-
-- Class components or non-hook patterns (should be functional + hooks only)
-- Inline styles (should use LESS with design system variables)
-- Missing loading states or error handling on data fetches
-- Accessibility gaps: missing alt text, aria labels, keyboard navigation
-- Hardcoded strings that should come from the API or config
-- Memory leaks: missing cleanup in `useEffect`
-- Props drilling beyond 3 levels (should use Context)
-- Missing key props in lists
-- Console.log left in production code
-
-### Omar — Performance
-
-Focuses on efficiency, caching, and resource usage.
-
-- Synchronous blocking calls that should be async (especially subprocess calls in request handlers)
-- Missing database indexes on frequently queried columns
-- Unbounded queries: `SELECT *` without `LIMIT` or pagination
-- Repeated identical subprocess calls that could be cached
-- Large file reads loaded entirely into memory
-- Frontend: unnecessary re-renders, missing `useMemo`/`useCallback` where expensive
-- Missing `timeout` on subprocess calls or external HTTP requests
-- Socket.IO events that broadcast too frequently
-
-## How to Review
-
-1. Determine the scope from `$ARGUMENTS` and read all relevant code
-2. For each reviewer, analyze the code **only through their lens** — don't overlap
-3. Rate each finding:
-   - **Fix** — Bug, vulnerability, or will break in production. Must address.
-   - **Improve** — Works but suboptimal. Should address.
-   - **Note** — Observation or suggestion. Nice to know, no action needed.
-4. Collect all findings
-
-## Report
-
-Create the `.reviews/` directory if it doesn't exist. Write to `.reviews/YYYY-MM-DD-review.md` (use today's date). If a file for today exists, append a counter: `YYYY-MM-DD-2-review.md`.
-
-```markdown
-# Code Review — YYYY-MM-DD

-**Scope:** <what was reviewed>
-**Files reviewed:** N

Subject: [PATCH 05/37] Mark CLI admin as setup; add login fallback UI

When creating an admin via the backend CLI, mark setup as complete by calling SettingsService.complete_setup so the web UI won't show the setup wizard. In the frontend, add a sign-in flow to SetupStepAccount when registration is disabled (e.g. an admin was created via CLI): pull login and registrationEnabled from Auth, implement handleLogin, show an informational banner, and keep the original register flow as handleRegister. In AuthContext, make checkSetupStatus retry a few times (with a short delay) if the backend isn't ready, and on exhausted retries assume a fresh install (needsSetup and registrationEnabled = true) to avoid locking out users while the backend initializes.

Subject: [PATCH 07/37] Add sidebar prefs, workflow & docs updates

Add user-configurable sidebar and initial workflow/environment features across backend, frontend, and docs.

Backend: store sidebar_config on User (JSON column), add get_sidebar_config / set_sidebar_config helpers, include sidebar_config in user.to_dict(), and validate/update sidebar_config in the update_current_user API (preset and hiddenItems validation).

Frontend: refactor Sidebar to compute visible items via a shared sidebarItems module and memoized grouping/rendering; add settings UI and sidebarItems (new components) and update settings styles to support sidebar configuration.

Docs & README: update README and ARCHITECTURE to document Workflow Builder, Environment Pipeline, and other new/renamed features; bump roadmap versions and reorder/expand roadmap phases to reflect Visual Designer, Automation Engine, pipeline, and monitoring work.

Overall: wires up end-to-end support for customizable sidebar preferences, surfaces them via API, and updates UI + documentation to reflect new automation and pipeline features.

 ### How ServerKit Finds Available Ports
 
+ServerKit automatically scans the database, Docker, and system sockets to find the first available port (starting from 8000) for new applications, ensuring no conflicts occur during deployment.
+
+---
+
+## Database Linking
+
+### How Apps Connect to Databases
+
+ServerKit automates the creation of databases and users, then injects the credentials as environment variables (`DB_HOST`, `DB_USER`, etc.) directly into the application container, allowing for seamless connectivity.
+
+---
+
+## Workflow Automation
+
+ServerKit includes a node-based visual workflow builder for automating server tasks.

Subject: [PATCH 08/37] Add workflow engine, models, API & UI

Introduce a full-featured workflow automation system: add WorkflowEngine service to execute workflows, background scheduler to trigger cron workflows, and croniter dependency. Extend Workflow model with automation fields (is_active, trigger_type, trigger_config, last_run_at, last_status) and add WorkflowExecution and WorkflowLog models. Add API endpoints to start executions, list executions, fetch execution details and logs, and persist execution records/logs. Implement frontend components for workflow nodes, config panels, and an execution history UI (multiple new React components) and wire minor builder UI imports. Note: database migrations are required to add new columns and tables.

Subject: [PATCH 09/37] Add workflow automation engine and triggers

Introduce a full workflow/automation subsystem: new WorkflowEngine with DAG validation/execution (Kahn's algorithm), logic-if branching, variable interpolation, script sandboxing (timeouts, output limits), retry semantics, notification nodes, and an in-process WorkflowEventBus for event-triggered workflows. Backend API updates include webhook trigger and validate endpoints, auto-generation of webhook IDs on create/update, and services emitting events (git push, health check failures, app stopped, monitoring alerts). Add Alembic migration to create workflow-related tables and bump VERSION to 1.4.0. Also update .gitignore, add GitHub issue/PR templates, quick-start script, and various frontend workflow panel/component adjustments to support the new automation features.

 Moving beyond static design to dynamic, event-driven automation. This turns ServerKit into a powerful automation hub.
 
-- [x] **Event Triggers:** Run workflows on Git push, health check failure, high CPU usage, or Webhook receipt.
-- [x] **Cron Integration:** Schedule workflows to run on recurring intervals (e.g., "Every Sunday at 2 AM, backup all DBs and rotate logs").
-- [x] **Cross-Server Actions:** "When Server A's database is backed up, sync it to Server B and notify Discord."
-- [x] **Logic Nodes:** If/Else conditions, loops, and custom Python/Shell script execution nodes.
-- [x] **State Machine:** Track workflow execution history, retries on failure, and execution logs.
-- [x] **Global Variables:** Pass data between workflow steps (e.g., take the output of a build step and pass it to a deployment step).
+- [x] **Visual Workflow Builder:** Node-based canvas with drag-and-drop nodes, connection validation, and config panels
+- [x] **Cron Integration:** Schedule workflows to run on recurring intervals (e.g., "Every Sunday at 2 AM, backup all DBs and rotate logs")
+- [x] **Manual Execution:** Trigger workflows on demand with optional context data
+- [x] **Execution History:** Track workflow execution status, per-node results, and timestamped logs
+- [x] **Script Nodes:** Custom Shell script execution nodes with output capture
+- [x] **Notification Nodes:** Send alerts via configured notification channels
+- [x] **One-Click Stack Deployment:** Deploy full infrastructure (databases, apps, domains) from a workflow diagram

+
+**Priority: High**
+
+Complete the workflow engine with proper execution logic, missing triggers, and production-grade reliability.
+
+- [x] **DAG Execution:** Full directed acyclic graph traversal with parallel branch support (replace current linear BFS)
+- [x] **Logic Node Evaluation:** If/Else condition evaluation with true/false branching
+- [x] **Variable Interpolation:** Pass data between steps using `${node_id.field}` and `{{placeholder}}` syntax in node configs
+- [x] **Webhook Triggers:** Register `/hooks/<webhook_id>` endpoint to fire workflows on incoming HTTP requests
+- [x] **Event Triggers:** Run workflows on system events (health check failure, high CPU/memory, git push, app stopped)
+- [x] **Notification Templating:** Message placeholder substitution (`${node_id.stdout}`, `{{workflow_name}}`) in notification nodes
+- [x] **Execution Timeouts:** Configurable timeout per node (1–3600s) to prevent hung workflows
+- [x] **Retry on Failure:** Configurable retry count (0–5) and delay per node
+- [x] **Circular Dependency Detection:** Kahn's algorithm validates graph on save and before execution
+- [x] **Script Sandboxing:** Timeout enforcement, output size limits, explicit `bash -c`/`python3 -c` execution

Subject: [PATCH 10/37] Add agent fleet management, discovery & updates

Introduce full agent fleet management and discovery features across backend, agent, and frontend. Backend: add AgentVersion and AgentRollout models, extend Server/ServerGroup/ServerCommand/AgentSession with fleet, queue and latency fields; implement AgentFleetService (bulk upgrades, staged rollouts, queued commands, retries, diagnostics) and DiscoveryService (UDP broadcast scan); add new servers API endpoints for fleet operations. Agent: add UDP discovery responder, agent:update handler to trigger updater, and wire updater.UpdateTo to install specific versions; extend protocol messages with discovery and agent:update types. Registry: deliver queued commands on agent connect and track heartbeat latency. Frontend: add AgentFleet page and route, plus API client updates. Also add SECURITY_AUDIT.md to .gitignore. These changes enable discovery, staged rollouts, offline command queuing with retries, and fleet health/diagnostics.

Subject: [PATCH 11/37] Fleet monitor + security and agent hardening

Adds cross-server Fleet Monitor endpoints and models, plus broad security and robustness improvements across agent, backend, and tooling.

Key changes:
- New fleet monitor API (endpoints for heatmap, comparison, alerts, thresholds, anomalies, forecast, search, exports, and Prometheus) and service skeleton.
- New DB models for ServerAlertThreshold and MetricAlert to support metric alerts.
- Agent discovery/registration hardening: HMAC-signed discovery requests, signature/timestamp validation, minimal discovery responses, HMAC-based unregister headers, and enforced command timeout cap in agent command handling.
- WebSocket and agent client TLS handling gated by SERVERKIT_INSECURE_TLS env var; added auth rate limiting on agent gateway.
- Docker-compose: parameterize agent image via AGENT_VERSION and avoid running as root by adding docker group access.
- Backend security & policy: tightened CSP script/style sources, request size limit, 2FA pending-token rejection on non-2FA endpoints, registration flow/guards, admin-only SSO admin routes via middleware, rate limits on sensitive endpoints, and logging for auth/2FA events.
- Database service hardening: identifier validation, avoid passing passwords on CLI (use env vars), safer subprocess usage, and docker exec handling improvements.
- CronService: command validation to prevent shell injection and run commands without shell=True; build_service and other subprocess usages updated similarly.
- Misc: .env.example notes clarified for encryption key generation, invitation token generation improved, agent registry timestamp window reduced, various logging and input validations added, frontend FleetMonitor page and styles stubbed in, and Vite/config/style updates.

Overall this commit implements fleet monitoring scaffolding and a set of security, validation, and operational improvements to make agent discovery, registration, command execution, and backend services safer and more robust.

-- [x] Anomaly detection — automatic baseline learning, alert on deviations
-- [x] Custom metric dashboards — drag-and-drop widgets, save layouts per user
-- [x] Metric correlation view — spot relationships between metrics across servers
-- [x] Capacity forecasting — trend-based predictions (disk full in X days, memory growth rate)
-- [x] Metrics export — Prometheus endpoint (`/metrics`), CSV download, JSON API
-- [x] Grafana integration guide and pre-built dashboard templates

-- [ ] Bulk apply — roll out template changes across server groups
-- [ ] Compliance dashboard — percentage of fleet in compliance per template
-
----
-
-## Phase 30: Multi-Tenancy & Workspaces (Planned)
-
-**Priority: Medium**
-

Subject: [PATCH 14/37] Add server templates with config drift detection and
 compliance

Phase 29: Template builder, library presets (Web/DB/Mail), template
inheritance, per-server assignment, drift checking via agent, auto-remediation,
bulk apply, and fleet compliance dashboard.

-## Phase 29: Server Templates & Config Sync (Planned)
+## Phase 29: Server Templates & Config Sync (Completed)
 
 **Priority: Medium**
 
 Define what a server should look like, apply it, and detect when it drifts.
 
-- [ ] Server template builder — define expected state (packages, services, firewall rules, users, files)
-- [ ] Template library — save and reuse templates (e.g., "Web Server", "Database Server", "Mail Server")
-- [ ] Apply template to server — install packages, configure services, set firewall rules via agent
-- [ ] Config drift detection — periodic comparison of actual vs. expected state
-- [ ] Drift report UI — visual diff showing what changed and when
-- [ ] Auto-remediation option — automatically fix drift back to template (with approval toggle)
-- [ ] Template versioning — track changes to templates over time
-- [ ] Template inheritance — base template + role-specific overrides
-- [ ] Bulk apply — roll out template changes across server groups
-- [ ] Compliance dashboard — percentage of fleet in compliance per template

Subject: [PATCH 15/37] Add multi-tenancy workspaces with member management and
 quotas

Phase 30: Workspace isolation, role-based membership (owner/admin/member/viewer),
workspace-scoped API keys, usage quotas, archive/restore, branding, and
super-admin cross-workspace view.

-## Phase 30: Multi-Tenancy & Workspaces (Planned)
+## Phase 30: Multi-Tenancy & Workspaces (Completed)
 
 **Priority: Medium**
 
 Isolate servers by team, client, or project. Essential for agencies, MSPs, and larger teams.
 
-- [ ] Workspace model — isolated container for servers, users, and settings
-- [ ] Workspace CRUD — create, rename, archive workspaces
-- [ ] Server assignment — each server belongs to exactly one workspace
-- [ ] User workspace membership — users can belong to multiple workspaces with different roles
-- [ ] Workspace switching — quick-switch dropdown in the header
-- [ ] Per-workspace settings — notification preferences, default templates, branding
-- [ ] Workspace-scoped API keys — API keys restricted to a single workspace

Subject: [PATCH 16/37] Add advanced SSL: wildcard, SAN, custom certs, health
 checks

Phase 31: DNS-01 wildcard certificates, multi-domain SAN certs, custom
cert upload, SSL health grading (protocols/ciphers), expiry alerts, and
configuration profiles (modern/intermediate/legacy).

Subject: [PATCH 18/37] Add Nginx advanced config: reverse proxy, load
 balancing, caching

Phase 33: Visual reverse proxy builder, upstream load balancing (round-robin,
least-conn, IP hash), proxy cache zones, rate limiting, header manipulation,
config syntax validation, diff preview, and per-vhost log viewer.

Subject: [PATCH 19/37] Add status pages with health checks and incident
 management

Phase 34: Public status pages, automated health checks (HTTP/TCP/DNS/ping),
component grouping, incident timeline, maintenance windows, uptime tracking
(24h/7d/30d/90d), status badges, and customizable branding.

 **Priority: Medium**
 
 Public-facing status page and automated health monitoring.
 
-- [ ] Automated health checks (HTTP, TCP, DNS, SMTP) with configurable intervals
-- [ ] Public status page (standalone URL, no auth required)
-- [ ] Status page customization (logo, colors, custom domain)
-- [ ] Service grouping on status page (e.g., "Web Services", "Email", "APIs")
-- [ ] Incident management — create, update, resolve incidents with timeline
-- [ ] Uptime percentage display (24h, 7d, 30d, 90d)
-- [ ] Scheduled maintenance windows with advance notifications
-- [ ] Status page subscribers (email/webhook notifications on incidents)
-- [ ] Historical uptime graphs
-- [ ] Status badge embeds (SVG/PNG for README files)

Subject: [PATCH 27/37] Backend fixes, API renames, and style utilities

Multiple coordinated changes: backend
- Ensure JWT identity is stringified (PyJWT 2.10+ compatibility).
- Allow relaxed CSP in debug (unsafe-inline + localhost/ws) for Vite dev tooling.
- Rename CloudServer.metadata -> server_metadata and update usages to avoid property conflicts.
- Enhance MigrationService to auto-add missing columns (SQLite-aware type mapping), create missing tables and log results.
- Add run_command helper that returns a simple stdout/stderr/returncode dict.

Frontend
- Rename numerous ApiService methods for clarity (e.g. getGitStatus -> getGitServerStatus, triggerDeploy -> triggerAppDeploy/triggerGitDeploy, getProcesses -> getSystemProcesses, nginx advanced test/reload renamed) and update pages to call the new APIs.
- Import Activity icon in WorkflowBuilder.

Styles
- Add Tailwind-like utilities.less and import it in main.less.
- Add spacing/color aliases to variables.less, new badge component styles, and layout/sidebar tweaks (page-container, header helpers, spacing/opac adjustments).

Overall: fixes compatibility issues, improves schema migration resiliency, clarifies API method names, and adds utility styles for newer pages.

Subject: [PATCH 28/37] Add security, logging, DB hardening & SCSS refactor

Broad refactor and hardening across backend and frontend:

- Standardize API error responses by removing legacy `success` flags and returning concise error payloads.
- Replace inline admin decorators with centralized middleware import (admin_required) in DB and Docker APIs.
- DatabaseService: add safer MySQL execution helpers and secure user-creation flow (hex-encoding, env-pwd usage) and improve pg drop to validate identifiers.
- Models: add eager-loading (subquery) for relationships and add indexes to frequently queried columns to reduce N+1 and improve performance.
- DockerService: add structured logging and error messages for better observability when Docker commands fail.
- Config: tighten ProductionConfig cookie settings (secure, httponly, samesite).
- Frontend: migrate many .less styles to .scss, add new security UI components and API client modules, update package metadata accordingly.
- Misc: add APP_IMPROVEMENTS.md to .gitignore.

These changes improve security, reliability, observability, and frontend styling consistency.

Subject: [PATCH 29/37] Refactor: move API service to services/api/index.js

Replace the monolithic frontend/src/services/api.js with a new module at frontend/src/services/api/index.js to better organize and modularize the API layer. The previous large api.js file was removed and its functionality has been relocated into the new directory-based module (index.js). Update any imports referencing frontend/src/services/api.js to import from frontend/src/services/api (or the new index path) as needed.

Subject: [PATCH 30/37] Introduce Modal component and lazy-load pages

Add a reusable Modal component (handles Escape key, focus trap and consistent markup) and refactor many inline modal implementations across the frontend to use it (EnvironmentVariables, LinkAppModal, QueryRunner, security tabs, GitConnectModal, ApiKeyModal, etc.). Implement React.lazy + Suspense for large pages and replace loading placeholders with a shared LoadingState; add route normalizations/redirects and tab-aware routes. Add new UI primitives (EmptyState, StatusBadge), an About settings tab, sidebar presets/appearance links and related sidebar logic, plus new styles. Also add the @rollup/rollup-win32-x64-msvc dependency to package.json.

Subject: [PATCH 31/37] Add Downloads and Status Pages tabs (lazy-loaded)

Move Downloads into Marketplace as a lazily-loaded tab and integrate it into the tab navigation (replace local tab state with useTabParam and register 'downloads' in VALID_TABS). Add lazy-loaded StatusPages to Monitoring, extend VALID_TABS and add the Status Pages tab and rendering via Suspense with LoadingState fallback. Also update App.jsx comment to reflect that Downloads was absorbed into Marketplace and adjust Spinner imports to expose LoadingState.

Subject: [PATCH 32/37] Refactor routes, sidebar and workflow panels

Replace many lazy imports/Suspense with direct page imports and expand route mappings (new pages, renamed routes and updated PAGE_TITLES). Simplify loading state to a basic placeholder and adjust Private/Public/Setup route behavior. Revamp Sidebar to support collapsible subItems, auto-expand parents based on location, per-item expand toggles, and updated icon/chevron usage; update sidebarItems data to include subItems for Servers, Domains, Files, Monitoring and Marketplace and simplify preset handling. Introduce a shared ConfigPanel component and migrate Logic/Notification/Script panels to use it (add icon/color, delete footer, improved form controls, hints and examples). Normalize node components (LogicIf, Notification, Script, Trigger) to use consistent icon/styling classes, status handling and layout improvements. Miscellaneous UI/UX tweaks and small refactors across workflow components and styles.

Subject: [PATCH 34/37] Add audit graphs, server selector & UI tweaks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Frontend and backend updates to improve activity visibility and multi-server support.

Backend: extend activity summary window to 90 days and add per-day series for the top user (top_user_daily) to the activity summary API.

Frontend:
- Activity tab refactor: rename feed→logs, add pagination, server-side audit log fetching, richer filters, icons, action formatting, details rendering, and improved loading/empty states.
- New ContributionGraph component + styles to visualize daily activity and per-user contributions; graphs injected into ActivityTab.
- Sidebar: separate manual vs auto-expanded state, auto-expand active parent, and persist preset switch locally while persisting to API in background.
- Dashboard: add server selector and remote-server metrics fetching, use remote metrics when a non-local server is selected, adjust polling and refresh semantics, and various UI/icon tweaks.
- Appearance tab: remove inline white-label UI; introduce a dedicated WhiteLabelTab component for custom branding.

Misc: add component and page SCSS files and small README updates describing new features and priority areas.

Subject: [PATCH 36/37] Expose is_admin and normalize UI classes

Add is_admin to User serialization so frontend can check admin privileges. Standardize frontend BEM modifiers to simpler utility classes across multiple pages (btn-primary, btn-sm, btn-danger, modal-header/modal-body/modal-footer/modal-close, etc.) and update various modals/buttons to use the new classes. Enhance DNSZones by introducing PROVIDER_CONFIG to provide provider-specific labels, placeholders, help text and extra fields (Route53 AWS keys/region), and adjust the zones page header UI. Add .text-muted utility to SCSS. These changes unify styling and improve DNS provider configuration UX.
