Fix downloads endpoint to show kept files and remove lyrics cache endpoint

- Downloads endpoint now shows both /app/downloads (cache) and /app/kept (favorited)
- Added location field to distinguish between cache and kept files
- Added cacheCount and keptCount to response
- Removed lyrics cache clear endpoint (no longer needed)
