Refactor error_response function for improved argument handling

- Enhanced the `error_response` function to support backward compatibility by normalizing arguments when positional arguments are misused.
- Updated various views to pass `None` for the `errors` parameter in `error_response` calls, ensuring consistent response formatting.
- Adjusted logging in `ContentSyncService` and `WordPressClient` to use debug level for expected 401 errors, improving log clarity.
- Removed deprecated fields from serializers and views, streamlining content management processes.
