[BE-API-032] be-api: Implement upload stats endpoint

Browse source 
- Added GetUploadStats method in TrackUploadService to calculate statistics from tracks table
- Standardized GetUploadStats handler to use RespondSuccess/RespondWithAppError
- Replaced c.Get with GetUserIDUUID helper
- Handler retrieves statistics: total_uploads, total_size, audio_files, image_files, video_files
- Updated UploadHandler to include TrackUploadService dependency
- Updated router to pass TrackUploadService to UploadHandler

Phase: PHASE-2
Priority: P2
Progress: 39/267 (14.6%)
