Refactor storage URL retrieval to use get_uploaded_file_url.

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.
