-etcd, Traefik, Grafana, Prometheus, Loki, Tempo, and BusyBox use pinned official

-`monitor_image_registry` only when the cluster requires private mirrors.
+etcd uses the official `gcr.io/etcd-development/etcd:v3.6.8` image. Its volume
+permissions init container and Traefik internal-stats sidecar use pinned
+BusyBox. The guided make flow derives sibling etcd and BusyBox mirror
