Refactor app.py and find_name_mismatches.py for improved user feedback and session state management

- Adjusted app.py to enhance the layout and flow of the name matching process, ensuring better user experience with tabbed navigation.
- Updated find_name_mismatches.py to provide clearer feedback when no changes are applied, improving user awareness of the matching process.
- Streamlined session state checks to ensure consistent execution of name matching functions, enhancing overall functionality.
