Enhance name matching logic in app.py and find_name_mismatches.py

- Updated app.py to check for existing session state before executing name matching functions, preventing unnecessary reprocessing and improving performance.
- Streamlined the return logic in find_name_mismatches.py to ensure accurate data handling while maintaining clarity and readability in the code.
