Add sanitized compose for caddy-vm and automation-vm stacks

Caddy (+ a truncated/sanitized example Caddyfile showing the mTLS +
Authentik forward-auth pattern without the real subdomain list),
Hawser, Gitea (private instance only, dropped the public-mirror
service - that's already its own public thing), Kestra (genericized
the ansible-repo/SSH-key bind mounts), Mosquitto, n8n, NetBox,
Node-RED.
