2309254fc9 FIX(repo): circular reference in app kustomizes 
- Comment out argocd.yaml in all app kustomization.yaml files
- Prevents circular reference when apps have 'path:' source (grafana,

b4ec13618a REFACTOR(repo): to independent app management 
- pattern
- monitoring/kustomization.yaml now only manages application.yaml (App
  of Apps)
- Each app independently manages its own ArgoCD Application via
  kustomization.yaml
- Apps are fully self-contained: argocd.yaml, namespace.yaml, and app-
  specific resources
- Cleaner separation: no central app list to maintain

  individual argocd.yaml files
- Better separation of concerns - each app is self-contained and
  independently managed
