Update projections handling in app.py for name matching

- Adjusted the logic to directly use the projections variable instead of session state for name matching, improving clarity and ensuring accurate data processing.
- Moved the salary data type conversion to follow the name matching operation, maintaining data integrity and enhancing code readability.
