Auto-fill for “Add Employee” flow

The "Add Employee" flow now features an auto-fill functionality to pre-populate form fields based on employers' previous entries. This feature automatically suggests data when you select a position, potentially filling up to 70% of the form.

- Position-based Auto-Fill: As you select a position (e.g., "Software Engineer") previously used for another case, relevant data will be automatically suggested in the new form.
- Previously Used Options: The nationality and position fields display past selections for quick and easy re-use.

Customizable Entries: All auto-filled data remains editable, allowing you to modify information as needed.
