Refactor contest data handling in app.py

- Removed the download functionality for contest data from DraftKings, streamlining the user interface.
- Simplified the file upload process by directly allowing users to upload contest files without the download option.
- Enhanced error handling for file uploads to improve user feedback when invalid files are uploaded.
