PVC manifests: add volumeName to bind new PVCs to existing PVs whose
old PVCs were accidentally deleted during Terraform->ArgoCD migration.
All PVs patched to Retain to prevent data loss on pod restart.

(Helm values don't support k8s secretKeyRef syntax) with correct
admin.existingSecret + admin.passwordKey pattern.
