Replaced calls to get_file_url with get_uploaded_file_url where appropriate. Added the get_uploaded_file_url method to the StorageProvider class and its implementations for more specific URL generation. Updated corresponding tests and API routes to reflect this change.
The `operation_id` field was added to the `generate_presigned_url` and `upload_file` endpoints. This enhances the OpenAPI documentation by providing unique identifiers for better API clarity and client generation.
Implemented endpoints for generating presigned URLs and handling file uploads. Added corresponding test cases to ensure proper functionality and error handling. Updated the main router to include the new uploads API.
