feat(homarr): add homarr-patches Application for PostSync probe fix

Separate Application (wave 9) applies Kustomize resources including
PostSync hook Job that patches probes after Helm deployment.

Required because:
- Main homarr Application (wave 8) uses Helm multi-source
- ArgoCD doesn't support Kustomize patches in Helm multi-source
- Chart doesn't expose probe configuration in values

Deployment sequence:
  Wave 8: homarr (Helm chart)
  Wave 9: homarr-patches (PostSync hook patches deployment)
