feat: chatbot screenshot-only eligibility detect, Sun Life/DentaQuest auto-check, chatbot attachment handoff to preauth; fix TuftsSCO preauth Selenium reliability

- Chatbot: submitting with only a screenshot attached (no text) now triggers the same
  "AI Detect & Check Eligibility" flow as the Copy Agent page
- detect-eligibility-info now also extracts the visible insurance payer name and picks
  Tufts SCO auto-check when both Sun Life and DentaQuest are detected, else MassHealth
- Chatbot-attached files are now handed off to both claim and preauth forms unconditionally,
  not just claims
- TuftsSCO preauth Selenium worker: verify-and-retry the Tooth field (typing was silently
  getting reset by duplicate-procedure-code warning banners), add a final re-verification
  pass across all rows, fix acknowledgement-checkbox targeting/verification, and verify
  the "Next step" click actually advances the wizard instead of trusting a blind click
