Simplify Helm templates to use .Values.fullname directly

- Replace complex fullname helper function with direct .Values.fullname reference
- Update all template files: ingress, deployment, service, secret, pvc, postgresql-statefulset
- Simplify serviceAccountName helper to use .Values.fullname
- This eliminates template rendering errors and makes naming more predictable
