feat: BCBS MA paper claim — fill 2024 ADA claim form; office NPI setting

- New GET /api/claims/:id/ada-form fills the 2024 ADA Dental Claim Form
  (J43024) with payer address, patient/subscriber, CDT lines, fees,
  missing teeth, billing (office) NPI and treating NPI; signatures blank
- "BCBS Claim (ADA Form)" button saves the claim and opens the PDF;
  Claim All routes BCBS patients to it; "Print ADA Form" in claim view
- Settings > NPI Providers: "Add Office NPI" (billing name, NPI, license,
  TIN) and optional per-provider license number
- Migration: office_contact billing fields, NpiProvider.licenseNumber
