fix: complete United Ucard claim flow and remember OTP device

- Click the first visible 'Next' button on the Patient Information step
  instead of a stale hidden one, so the wizard advances after member select
- Read procedure fee from totalBilled/billedAmount (matching every other
  claim worker) instead of a fee key the frontend never sends
- Implement claim confirmation PDF capture + claim number extraction
- Check "Remember this device" on the OTP page so future logins skip OTP
