REFACTOR(postgresql): restructure pgweb

- and pg-dev folder str...
- Remove argocd/, helm-values/ subdirectories
- Move files to parent directory with standardized names
- Add namespace.yaml to both apps with Goldilocks labels
- Preserve vault/ subdirectories (pgweb: 3 files, postgresql-dev: 1
  file)
- Update main kustomization.yaml to reference argocd.yaml files directly
- Update postgresql-dev helm valueFiles path
- Comment out argocd.yaml in each app's kustomization.yaml to prevent
  circular reference

Applications restructured:
- pgweb
- postgresql-dev
