fix: AI claims/preauths keep all codes past 10; reuse CCA/DentalHub Chrome

- Claim form: AI claim/preauth prefill adds rows beyond the initial 10
  instead of dropping codes 11+
- CDT lookup: "D6010 #5, 9, 11, 12" expands to one line per tooth, and
  the chat graph rebuilds such lists from the message if the LLM drops items
- Eligibility: match an existing patient by name+DOB when the insurance ID
  changed (e.g. MassHealth → CCA) instead of creating a duplicate patient
- CCA PreAuth: services grid scrolls to reach rows 11+
- CCA and Tufts SCO PreAuth: tentative service date = today + 3 days
- CCA (eligibility/claim/preauth) and DentalHub (claim/preauth): keep Chrome
  open, blank and minimized, after a job so the next job reuses it
