[codex] Add Docker casino skeleton

[larsenevansdeveloper]

What changed

• Added a clean Docker Compose casino skeleton with nginx, frontend, API, Postgres, and Redis.
• Added a Vite React frontend with lobby, demo wallet, fake game round flow, and admin control room.
• Added an Express fake casino API with seeded demo data, wallet ledger entries, signed provider callbacks, idempotent provider events, rollback protection, admin endpoints, and audit logs.
• Added Docker/nginx config, env examples, ignore rules, and usage documentation.
• Stabilized the existing AdminLTE preview lint/runtime issues and added lock files for reproducible setup.

Why

The upstream public repository is only a preview and lacks the full Laravel casino app, database dump, installer, and websocket backend. This adds a separate runnable foundation that can evolve independently without depending on the incomplete preview tree.

Validation

• npm run check in apps/api
• npm audit --audit-level=moderate in apps/api
• npm run build in apps/frontend
• npm audit --audit-level=moderate in apps/frontend
• docker compose config
• docker compose build
• docker compose up -d
• curl -fsS http://localhost:8080/health
• curl -fsS http://localhost:8080/api/health
• curl -fsS -H "X-Admin-Token: dev-admin-token" http://localhost:8080/api/admin/dashboard
• php -l over available PHP files
• composer validate --strict in back
• npx grunt jshint in back

Notes

This is development-only scaffolding. Real-money use still needs licensing, certified game/provider integrations, KYC/AML, secure auth, production secrets, monitoring, and legal review.
