WordPress resolves its own public domain to the server's public IP from
inside the container, so REST API / WP-Cron / Site Health loopback
requests depend on hairpin NAT, which times out (cURL error 28) on many
hosts. Pin the site domain to the dokploy-traefik container IP in
/etc/hosts at startup (with retries, since Traefik joins the compose
network shortly after the container starts) so loopback traffic stays
inside the Docker network for both HTTP and HTTPS. No-op fallback when
dokploy-traefik is not resolvable.
