fix(homarr): add proper probes via Kustomize patch

Chart version 8.23.0 doesn't support probe customization via values.
Using strategic merge patch instead.

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

App initialization timeline:
  0-5s: DB migrations, Redis startup
  6s: WebSocket server ready
  27-30s: Icon cache populated (27k+ icons)
  30s+: Analytics cron initialized, fully operational
