- Replaced common upload handler and service with Qiniu-specific implementations in main.go and route registration.
- Deleted outdated upload_handler.go and qiniu_service.go files to streamline the codebase.
- Updated route definitions to utilize the new Qiniu upload handler for improved file upload management.
