Fix VerificationRecord validation errors for classification values

- Add validation for classifier_decision and ground_truth_label in all interfaces
- Ensure only valid values (green, yellow, red) are used, fallback to 'green'
- Fix enhanced_dataset_interface.py: validate classification results
- Fix file_upload_interface.py: validate classification results
- Fix manual_input_interface.py: validate classification results
- Resolves 'Field must be one of [green, yellow, red], got unknown' errors
