- Make appointmentId nullable/optional in Prisma Zod schema via @zod rich
comment so claims can be submitted without an existing appointment
- Convert undefined appointmentId to null in all claim form handlers and
the backend claim creation endpoint
- Add AI classifier rule for expanding one procedure across multiple
comma-separated tooth numbers (e.g. "post/core on #23, 24, 25, 26")
- Add "post/core" (slash) alias to CDT lookup maps
