Manage Gondulf and StarPunk with Ansible

Both were hand-deployed to /opt/stacks. Templates match the live setup
and keep the same stack dirs and volume names, so data stays put.
Secrets come from the vault; .env and the StarPunk compose file are now
0640 root:docker instead of the broken 1204 mode. Adds their DNS
records to dns.yml and drops the dead godulf. Caddy route (no DNS).
