feat: MassHealth PDF import auto-pays full balance + patient name fix

- PDF import now marks payments as PAID when MassHealth patient's
  mhPaidAmount >= totalBilled (no patient balance)
- Newly created patients from MH vouchers get insuranceProvider = 'MassHealth'
- Existing patients with blank insuranceProvider get it filled on import
- Fix: update patient name from PDF if existing record has empty name
- Various frontend/selenium/route updates
