- Auto-seeds 3 Highland Dental Studio defaults on first use per user
- LabRxModal: template picker, inline rename, up/down reorder, full
  template form with sections (Template Name / Lab Info / Case Details)
- RX popup: Tooth Number, Shade, Due Date, Doctor (from NPI providers),
  Instructions pre-filled with "Please make / Thank you!", print output
- lab-rx-templates.ts config file for future git-managed additions
