fix(webhooks): Load collapsed by default, add webhook metrics to status panel

- Fixed webhooks section to load collapsed (content hidden, toggle arrow reset)
- Added webhook metrics card to status panel for admin users:
  - Shows Sonarr/Radarr enabled/disabled status
  - Shows events received and polls skipped counts
- Updated /api/dashboard/status endpoint to include webhook metrics
- Metrics are aggregated from all Sonarr/Radarr instances

server/routes/dashboard.js
