chore: add Supabase PVC quota diagnostics and improve ingress handling

- Added PVC quota error detection with detailed logging in `deploy.sh`.
- Enhanced ingress readiness checks with additional Supabase ingress resources.
- Updated Helm templates to standardize and always enable ingress for API and Studio.
