Implement a channels system for notifying teams via external providers
(Discord, Slack, Teams, Google Chat, Telegram, Matrix, webhook) when
lifecycle events occur (capsule/template/host state changes).
- Channel CRUD API under /v1/channels (JWT-only auth)
- Test endpoint to verify config before saving (POST /v1/channels/test)
- Secret rotation endpoint (PUT /v1/channels/{id}/config)
- AES-256-GCM encryption for provider secrets (WRENN_ENCRYPTION_KEY)
- Redis stream event publishing from audit logger
- Background dispatcher with consumer group and retry (10s, 30s)
- Webhook delivery with HMAC-SHA256 signing (X-WRENN-SIGNATURE)
- shoutrrr integration for chat providers
- Secrets never exposed in API responses
