feat: add schedule column labels, office hours enforcement, and appointment move fix

- Schedule columns default to labels A–F (localStorage, per-browser, click to rename)
- Settings → Advanced → Office Hours: configure Doctors (A-C) and Hygienists (D-F) AM/PM hours per weekday
- Gray out schedule slots outside office hours; override dialog for manual exceptions
- Override Office Hours toggle: select specific dates where all slots are open
- Fix appointment move: send only real DB fields to avoid Zod strict-mode rejection of computed fields (hasProcedures, hasClaimWithNumber)
- Fix backend PUT /appointments: safe error logging to prevent Prisma error crashing Node inspect
- Add OfficeHours Prisma model and GET/PUT /api/office-hours route
