Refactor contest data loading logic in app.py to enhance session state checks

- Updated the condition for loading contest data to ensure it only occurs when both 'Contest_file' and 'Adj_Contest' are absent, improving session state management.
- Streamlined the process of loading contest data and providing user feedback, enhancing overall user experience.
