Rename model files with descriptive names and timestamps

- Rename sklearn_model.joblib → vntc_classifier_20250927_161550.joblib
- Rename sklearn_model_uts2017_bank.joblib → uts2017_bank_classifier_20250927_161733.joblib
- Update use_this_model.py to use new descriptive filenames
- Timestamps indicate training date and time for better versioning
