fix: update pg hostname and PVC claim names

- Change hostname from vkvm-us1 to zgocloud-us1
- Update persistent volume claim name from pg-data-local-vkus1-pvc to pg-data-local-zgus1-pvc
- Modify storage class name to local-zgus1

These updates ensure that the PostgreSQL deployment references the correct
Kubernetes node and persistent volume, aligning with the current
infrastructure and deployment strategy.
