The Ombi API returns requestedUser as an OmbiUser object instead of a string.
Add extractRequestedUser helper to extract username from various fields
(alias, userAlias, userName, normalizedUserName) with fallback to legacy string format.
Update client and server routes to use the helper for consistent username extraction.
- Add Ombi requests tab UI with movie/TV request display
- Add showAll parameter support for Ombi requests (API and SSE)
- Add Ombi webhook panel with enable/test functionality
- Add Ombi webhook status endpoint with metrics
- Add Ombi webhook test endpoint
- Change GET /api/ombi/requests to use OmbiRetriever instead of cache
- Add Ombi webhook state and API functions to frontend
- Update SSE payload to include Ombi baseUrl and requests
1. Fixed download client collision:
- SABnzbd client with id 'i3omb' was being overwritten by qBittorrent
- Now uses unique key ':' like the arr retrievers
2. Fixed webhook metrics showing 0:
- instanceName from webhooks is generic ('Sonarr', 'Radarr')
- Not the configured instance name ('i3omb')
- Now updates metrics for ALL instances of that type
- Added POST /api/webhook/sonarr and POST /api/webhook/radarr endpoints
- Implemented webhook secret validation via SOFARR_WEBHOOK_SECRET environment variable
- Added logging for all incoming webhook events using existing logToFile utility
- Returns HTTP 200 immediately to prevent webhook retries
- Mounted webhook routes before CSRF middleware (called by external services)
- Non-breaking: no changes to polling, caching, SSE, or any existing behavior
- Lays groundwork for Phase 2 (cache + SSE integration) without implementing it yet
