Minimal Nexus EMR profile for Slot resources — an individual bookable time window owned by a Schedule. Slots are materialised from recurring templates (Phase 1: OscarPro scheduletemplate rows) into concrete date+time instances. Booking clients select a free Slot, create an Appointment referencing it, and the booking system transitions the Slot's status.
