/**
 * #3269: webhooks could not target a private/internal address (10.x, 192.168.x, a
 * docker-internal host) — common for self-hosted automation (n8n, Home Assistant).
 * The webhook URL guard now allows private targets only when the operator opts in via
 * the existing `OMNIROUTE_ALLOW_PRIVATE_PROVIDER_URLS` flag (default OFF). Protocol and
 * embedded-credential checks stay unconditional.
