fix(grafana): wire orphan status-onion-service.yaml into kustomization

The file existed in the workloads/grafana directory but wasn't referenced
in resources, so the OnionService CR for the public status dashboard was
never applied. Adding it brings the onion address listed on
onion.makeitwork.cloud (7m3fv4pd5m...onion) live again.
