- Clear HealthProbe on StartStack/RestartStack so stale unhealthy state
isn't re-applied by RefreshStatus
- Use 10s probe interval for unhealthy/new stacks (nil HealthProbe probes
immediately on next tick), switch to normal 5m interval once healthy
- Scheduler frequency 1m → 10s to support fast probing

Add network-level health probing from the controller to deployed apps.
The controller probes containers over the shared Docker network and
overrides stack state to "unhealthy" if the service isn't responding.
Three probe types: http (any response = alive), api (validates status
code and body content), tcp (port reachability). Configured per-app
via healthcheck: section in .felhom.yml. Runs every minute, per-app
interval defaults to 5 minutes.
This replaces Docker-level healthchecks for distroless images (e.g.
Vikunja) that lack shell utilities, and complements existing Docker
healthchecks for other apps.
