Environment Overview / Activity on the Home Page

[A-Artemis]

Background & Motivation

When a colleague picks up someone else's Geti environment, they lack an at-a-glance overview: which pipeline is running, which projects have trained models, and what recent activity occurred. The home page (ProjectList in application/ui/src/features/project/list/project-list.component.tsx) currently shows only a project grid and version number.

Proposed Solution

Add a lightweight environment overview banner/panel at the top of the home page summarizing the single most important collaboration signals, built entirely from existing data (projects list + pipeline status + models list).

Functional Requirements

1. Active pipeline summary
   • The overview shall prominently state which project (if any) currently owns the running pipeline, linking to it. Data comes from active_pipeline on ProjectView (application/backend/app/api/schemas/project.py), complementing the "Pin & Control the Active Pipeline Project" feature.
2. Counts by task type
   • The overview shall show how many projects exist per task type, giving newcomers immediate context for instructions like "all detection projects".
3. Recently updated projects
   • The overview shall surface the most recently created/updated projects using created_at from ProjectView.
4. Non-intrusive
   • The overview shall be collapsible and shall not obstruct the existing project grid workflow.

Affected Areas

• UI: application/ui/src/features/project/list/project-list.component.tsx (new overview panel component)
• Backend (existing, no change expected): application/backend/app/api/routers/projects.py, application/backend/app/api/routers/pipelines.py

Acceptance Criteria

• The overview shows which project owns the running pipeline (with a link), or nothing when idle.
• The overview shows project counts per task type.
• The overview lists the most recently created/updated projects.
• The overview is collapsible and does not obstruct the project grid.
• The overview is built from existing API data (no new backend endpoints required).
