feat: United/DentalHub claim submission automation and patient list sync

- Add full Selenium automation for United/DentalHub claim submission
  (steps 1-8: login, OTP, patient search, practitioner page, code entry,
  other coverage No, attachments, submit, Status & History PDF)
- Consolidate UnitedDH siteKey to UNITED_SCO throughout app
- Fix procedure date overwrite with Ctrl+A+Delete before typing service date
- Fix OTP popup reliability: emit every poll (no throttle)
- Fix Chrome session persistence: only clear cookies on startup
- Add touchPatient() to storage: claim submission now pushes patient to
  top of list across eligibility, claims, and documents pages
