neptun: serve Headplane at vpn.mgaction.town/admin, auth via Zitadel OIDC

Path-route Headplane under /admin on the same vhost as headscale instead of
its own subdomain - Caddy handle blocks split on the prefix, headscale gets
everything else. base_url drops to the site root since Headplane appends
/admin (and the OIDC callback path) itself.

Wire Zitadel as the OIDC provider. client_id/client_secret/the headscale
API key can't be real until Zitadel and headscale are actually deployed and
an application/key exist, so those are REPLACE_ME placeholders for now
(documented in services/headplane.nix) - direct API-key login stays enabled
as a fallback so this can't lock anyone out in the meantime.
