Webhooks hardcoded parseAndValidatePublicUrl, which blocks any RFC1918/loopback host —
breaking self-hosted setups that legitimately point webhooks at internal services
(n8n, Home Assistant, a LAN box). Provider URLs already had an opt-in
(OMNIROUTE_ALLOW_PRIVATE_PROVIDER_URLS); webhooks now reuse it.
- outboundUrlGuard: add parseAndValidateWebhookUrl — gates the private-host check on
arePrivateProviderUrlsAllowed() (default OFF); protocol + embedded-credential checks
stay unconditional.
- swap all webhook call sites (create/update/test/validate-url + dispatcher x2) to it.
Regression test: tests/unit/webhook-private-optin-3269.test.ts (RED before, GREEN after);
existing webhook SSRF/dispatcher suites stay green (33/33).
