curo1305 3248607790 Add service health checks and dynamic Apps page

Backend polls each registered service's /health endpoint every 30 s via a
background asyncio task. GET /api/services exposes the live status snapshot.
The Apps page now renders from this endpoint — showing "Unavailable" (dimmed,
non-clickable) when a service is registered but its container is unreachable.

2026-04-17 — Service health checks and dynamic Apps page

Timestamp: 2026-04-17T00:00:00Z

Summary

Added a background health-check system to the backend that polls each registered feature service every 30 seconds. The Apps page now renders dynamically based on live service status — showing "Unavailable" when a service is registered but its container is unreachable.
