fix(settings): update CFDM sync tests and improve error handling

Renamed test cases for clarity and added new tests for handling missing CFDM URL and token scenarios. Removed unnecessary checks in the sync request function to streamline the process. Updated integration form to ensure proper boolean handling for settings. Enhanced sync button behavior based on saved credentials.
