Subject: [PATCH] feat(vms): add SSH key + qemu-guest-agent to UniFi VM for
 ops/debugging

The first UOS bring-up left no way into the guest (cloud-init set no
credentials), so the in-guest UOS install couldn't be observed. Add:
- ssh_authorized_keys (public key, safe to commit) on the default ubuntu user
- qemu-guest-agent (KubeVirt AgentConnected + virtctl guest access)
- tee the install-uos output to the serial console + /var/log/uos-install.log,
  and record the installer exit code, so the install is observable.
