Add an opt-in webhook notification for container-automation events (image
update, rollback, update-failed, auto-heal restart), plugging into the existing
Notifier seam in notify.go.
- Settings: new ContainerAutomation.Notification.WebhookURL (shared across
update + heal), persisted and validated in the settings update handler
(optional; http/https only; accepts the {{message}} placeholder).
- webhookNotifier reads the current URL from the datastore per event (UI changes
take effect without a restart). If the URL contains {{message}} it substitutes
the URL-encoded message and issues a GET; otherwise it POSTs the message as the
body. Delivery, the env/stack name lookups, and any panic run in a goroutine
under recover() with a 10s timeout — strictly best-effort, never blocks or
crashes the automation daemon. multiNotifier fans events to logNotifier +
webhook and isolates a panic in any one notifier.
- Message format (maintainer's spec):
Environment | <env>
Stack [<name>] (Container [<name>] for non-stack events)
Update [<name>]: <old> -> <new>
Auto-heal: 'Auto-heal: restarted unhealthy container'.
- New NotificationPanel in settings to configure the URL.
