Make email field nullable on Pathfinder model

- Updated Pathfinder model to make Email property nullable
- Removed [Required] attribute from Email in DTOs
- Updated PathfinderValidator to only validate email format when provided
- Added database migration to make email column nullable and enforce first_name/last_name as required
- Updated validator tests to reflect email is now optional
