Align Kubernetes ports with Docker Compose configuration

- Frontend: Changed NodePort from 30080 to 3000 (matches Docker port)
- Backend: Changed NodePort from 30081 to 5001 (matches Docker port)
- Keycloak: Changed NodePort from 30082 to 8080 (matches Docker port)
- Updated ConfigMap URLs to use new ports
- Updated NEXTAUTH_URL to use port 3000

This ensures Kubernetes deployment uses the same ports as Docker Compose
for consistency across environments.
