upgrade Home Assistant 2024.5.4 → 2026.5.4

Bump the homeassistant image to 2026.5.4 (latest 2026.5 patch) and adjust
the healthcheck for modern HA:

- swap the probe from /api/ (now requires auth, returned 401 → spurious
  "unhealthy") to the auth-free /manifest.json
- set start_period to 2m; the recorder schema migration (43→48) completed
  in milliseconds on this 149M SQLite DB, so the temporary 30m headroom
  used during the upgrade is no longer needed

Verified post-upgrade: container healthy, version 2026.5.4, local
/manifest.json 200, reverse proxy 200, trusted_proxies /12 validated.
