Type of change

  • 🐛 Bug fix
  • 🚀 New feature
  • ❓ Other (please specify)

Description

Part 4/4 of #268. Adds a Health page to the application sidebar (/applications/$id/health), following the mockup in the issue.

  • Header: current status badge, "since …", and a 24h / 7d / 30d range switch (default 30d). The range is kept in the URL (?range=).
  • Stat cards: availability, downtime, incidents (with the longest one), no data.
  • Availability bar: one bar per bucket, colored by status, with no-data bars striped. The tooltip shows the time range and a per-status breakdown. Includes a legend and a note that no data isn't counted.
  • Incidents table: status, start, duration (with an "Ongoing" badge), and context. Context covers: agent offline (with the agent name), after deploy <commit> / after image update, the failing services, and "all containers are stopped".
  • Updates live through SSE and refreshes every 60s, since the bars move over time.
  • Translations for en and de. An e2e test checks the API and the page after the existing runtime-health tests (unhealthy + stopped).

Closes #268
