feat(matches): show both manual match requests and auto recording suggestions

Backend:
- Extend GET /api/matches to include RecordingSuggestions alongside Match objects
- Add 'type' field: 'manual' for user-created matches, 'auto' for algorithm suggestions
- Fetch suggestions where user is dancer (to be recorded) or recorder (recording others)
- Transform suggestions to match format with partner info
- Support status filtering for both types

Frontend:
- Display 'Auto' (purple) or 'Manual' (gray) badge on match cards
- For pending auto suggestions: show 'Go to Records' button instead of Accept/Reject
- For accepted auto suggestions without slug: show 'Chat not available yet'
- Only allow Accept/Reject actions on manual match requests
