Generic webhook notification delivery configured via the notify_webhook settings key — no new schema. Fires on monitor up/down transitions (pending stays silent), domain expiry, domain expiring, and TLS cert expiring; dispatch is async and failures are logged, never fatal. POST /api/notify/test verifies configuration; Settings dialog gains a webhook URL field with save + send-test. Payload carries event/name/text/content/message so Slack, Discord, ntfy, and custom receivers all work.
