REFACTOR(repo): restructure monitoring folder

- and add namespace resou...
- Remove argocd/, helm-values/, ingress/ subdirectories
- Move files to parent directory (argocd.yaml, helm-values.yaml,
  ingress.yaml)
- Update helm valueFiles paths in ArgoCD Applications
- Add namespace.yaml to all applications with Goldilocks labels
- Update destination namespaces to match folder names
- Update kustomization.yaml files to reference new structure
