fix(homarr): patch probes via PostSync hook

Chart v8.23.0 (homarr-labs/charts) doesn't support probe customization.
All attempts failed:
- probes.liveness.spec: ignored
- controller.probes: ignored
- livenessProbe.enabled: ignored

Solution: PostSync hook Job patches deployment after Helm sync.

Probe config:
- Liveness: 60s initial, 30s period, 5s timeout
- Readiness: 45s initial, 15s period, 5s timeout

App needs 30-45s for DB migrations, Redis, icon cache (27k+ icons).
