wolf-pair has no login of its own — Authelia via Caddy is the only
protection option offered for it — but UFW opened its port to the
whole internet unconditionally, before the Caddy/Authelia prompt even
ran. Same gap just fixed for the Asterisk web admin: reachable
straight over the bare port regardless of Authelia.
Reordered so the Caddy decision happens first, and scope the port to
caddy_net's subnet via ufw_allow_from_caddy_net() instead of leaving
it open to 0.0.0.0/0 when Caddy fronts it locally. Also enables UFW
via ensure_ufw_enabled() like the Asterisk services.
