fix: allow letters in insurance ID; add patient state (default MA)

- Backend insurance ID check now accepts letters + digits (BCBS IDs have
  a letter prefix), matching the frontend schema; create route validates
  the normalized body
- Patient.state column (default "MA") with State select on the patient
  form; ADA claim form uses the patient's state instead of the office's
- Rebuild stale packages/db compiled .js so the runtime schemas include
  new fields (state, office billing NPI fields, Telnyx settings)
