feat(scripts): add create, delete, and recreate actions for CloudNative-PG initialization

- Introduced new script commands to manage CloudNative-PG clusters (`create`, `delete`, `recreate`).
- Updated default namespace to `prole` and refined variable handling for cluster name.
- Adjusted kustomization.yaml to reference `prole-db.yaml` for consistency in manifests.
