debug: Add debug output to track result callback data flow

- Add debug prints in combined_result_callback to see received data
- Add debug prints in update_inference_results to track GUI updates
- Fix tuple order in terminal formatting to match actual (probability, result) format
- This will help identify why results show in terminal but not in GUI
