feat: Select Procedures flow, batch-column NPI provider fix, auto PDF save

- Add 'Select Procedures' right-click option on appointment page (separate from Claims/PreAuth)
- Select Procedures form saves CDT codes + NPI provider to AppointmentProcedure storage
- Remove Save button from insurance claim form; Claims/PreAuth opens for insurance submission only
- Claims/PreAuth auto-prefills from saved procedures including NPI provider
- Batch-column: procedures npiProviderId takes priority over stale claim npiProviderId
- Batch-column: auto-save PDF to patient Documents after successful submission (no socket needed)
- Add npiProviderId column to AppointmentProcedure table (prisma db push)
- Fix 'invalid db creation invocation': guard staffId, npiProviderId, procedureDate as Date object, totalBilled NaN guard
- Add full error logging to batch-column catch block
