feat: add Remaining/Third Party columns, toggle PDF viewer, retire CMSP as separate insurance type

- Add remainingBenefit and thirdPartyInsurance columns to Patient; extract both
  from the MassHealth accumulator/member-detail pages during the eligibility
  check and surface them in the eligibility table
- Add an updated-date display and a toggle to suppress the post-check PDF
  viewer popup (default off) on the insurance eligibility page
- Rename CMSP-prefixed PDF filenames and UI copy to MH, since CMSP and MH now
  share the same worker
- Fold CMSP into MassHealth/MH across patient/claim insurance-type dropdowns
  and the chatbot's eligibility routing, since they're the same insurance
- Remove auto-download of saved eligibility PDFs; downloading is now manual
