fix(tests): correct mock patch targets in google_drive coverage tests

- Change @patch("app.api.google_drive.get_google_drive_service") to
  @patch("app.tasks.upload_to_google_drive.get_google_drive_service")
  because the function is imported locally inside the endpoint function
  body, not at module level
- Replace patch.object(type(settings), "google_drive_use_oauth", ...)
  with patch("app.api.google_drive.getattr", ...) because Pydantic v2
  models don't expose fields as regular class attributes
