fix: Use app-cluster target pattern for Cloud Deploy

Updates target naming to match the actual Cloud Deploy infrastructure.
The pipeline uses a single unified target (e.g., webapp-cluster) for all
environments instead of separate targets per environment.

Different environments (dev, preview, qa) deploy to different namespaces
on the same cluster target.
