infra: relocate docker-30 compose stack under vms-home/, add garage and frisbee-drills

Move the docker-30 service definitions (gitea, kanidm, vault, zot,
nginx, lab-proxy, maru-hleda-byt, fuj-management) into vms-home/ to
match the naming convention used for other hosts, and add the new
garage object-storage and frisbee-drills services alongside it.
