feat: DDMA claim submission with OTP, PDF, claim number extraction

- Add full DDMA claim Selenium flow (steps 1-8): search patient, open
  member page, create claim, fill form, attach files, next, submit,
  extract claim number and save confirmation PDF
- Add fee schedule price-mismatch dialog for all claim buttons (MH,
  CCA, DDMA, United, Tufts, Save) with optional price update to JSON
- Add OTP modal for DDMA claim when session expires, mirroring
  eligibility OTP flow
- Close Chrome after claim submission via quit_driver() (session
  preserved in profile)
- Move Map Price button between Direct Submission and procedure table,
  right-aligned above Billed Amount column
- Add fee-schedule update-price backend route
- Add DDMA claim processor with claimNumber/pdf_url result handling
