feat: Altus Dental eligibility check and ADA paper claim/preauth

Eligibility (no OTP, fresh browser per run like MH): logs in, opens Benefits &
Claims Information, searches by Subscriber ID (or Subscriber Last Name via
"Click Here"), First Name and DOB, picks the matching row from the patient list,
sets ACTIVE/INACTIVE from the Coverage range, reads Group Number into the
patient's Group Number, opens View Details for the last name and plan name,
and saves the details page PDF to the patient's Eligibility folder. A patient
switching plans is matched by name + DOB so Altus overwrites the old insurance
instead of creating a duplicate.

Claims: Altus uses the same 2024 ADA form as BCBS with the Altus payer address
(P.O. Box 1557, Providence, RI 02901-1557). Adds Altus Claim/PreAuth (ADA Form)
buttons, Claim All and AI queue routing, Print ADA Form in the claim viewer, and
an Altus fee schedule (copied from BCBS).
