fix(demo-gymburgdorf): route cross-host ForwardAuth via dedicated outpost FQDN
Storage Traefik calling the public auth.gymb.* FQDN hit Authentik's ASGI
handler, which 404s the /outpost.goauthentik.io/auth/traefik path. Add a
dedicated outpost.auth.int.gymb.* FQDN outside authentik_domains so the
request falls through to the embedded outpost, pinned to the application
host via traefik_extra_hosts to stay on the LAN.

- authentik: add authentik_outpost_domains; allow users group on drawio
  proxy so the Nextcloud drawio iframe works for non-admins
- garage: point webui ForwardAuth at the new outpost FQDN
- homarr: use public OIDC issuer to match the iss claim, enable
  auto-login, pin auth FQDN to LAN via extra_hosts
- opnform: intercept / and /login for SSO, keep break-glass bypass
- drawio: align comments with admins+users allow-list
