feat: add PersistentVolume for CMS uploads + apply manifests in CI/CD

- Add k8s/staging/ and k8s/production/ deployment manifests
- PVC 20Gi for /app/Uploads (file uploads persist across pod restarts)
- FileStorage__UploadPath env var set to /app/Uploads
- Replicas reduced to 1 (ReadWriteOnce PVC)
- Pipelines now: create namespace → apply manifests → restart/update
