Update outdated image versions across test manifests and add tracking
to build/dependencies.yaml for version drift detection via zeitgeist:
- agnhost: 2.32/2.53/2.54/2.57 → 2.61 (latest)
- etcd: 3.2.24 → 3.6.7-0
- kitten/nautilus BASEIMAGE: agnhost 2.57 → 2.61
and added etcd statefulset reference to existing etcd entry.
