refactor(playbooks): host-generic GPU host + GPU LXC playbooks for nh3-ml1

- esh-pve-nvidia-host -> pve-nvidia-host: headers/dkms/build-essential step,
  nouveau blacklist + guarded unload (refuses if nouveau bound a device)
- esh-ml1-lxc -> gpu-lxc: host vars have no defaults (elway aborts on undefined),
  rootfs storage/startup order parameterized, CT kept out of all-guests vzdump jobs
- embed-rerank: Homepage labels take HOST_NAME/HOST_IP, defaults = esh-ml1
