feat: add BCBS MA eligibility check with OTP flow

- New Selenium worker (fresh Chrome per run, no persistent session)
  login → OTP modal → eTools → ConnectCenter → Verification →
  New Eligibility Request → fill form (NPI, member ID, DOB) →
  Expand All → CDP PDF back to app
- Backend route fetches BCBS_MA credentials + provider NPI from settings
- Frontend OTP modal with 6-digit code entry
- BCBS MA added to insurance credentials dropdown in settings
