Refactor name matching logic in `find_name_mismatches.py` to improve data handling

- Updated the function to return both `contest_df` and `projections_df` for better data management.
- Enhanced name matching by ensuring all occurrences in `contest_df` are updated when a match is found.
- Improved user feedback messages to clarify the matching process and outcomes.
