- Auto-infer appointment type from CDT codes with priority rules (endo > implant > crown > ...)
- typeLocked flag prevents auto-overwrite when user manually sets type
- Show appointment type label and procedure codes on schedule cards
- Background sync on /day route retroactively fixes stale appointment types
- Fix PUT /api/claims/:id to save claimFiles (previously silently dropped)
