This will add all Instructor Candidates and Assessor / Senior Instructors from the MOU roster to the IW registrations list (as Pending). People already on the list will not be duplicated.

This will add everyone in Faculty Responses whose attendance status is Confirmed (pending and declined responses are left out) to the IW registrations list, already marked Confirmed — no separate confirm step needed here. People already on the list will not be duplicated.

Assessors and Senior Instructors self-confirm their attendance at iw-rsvp.html (attendance is not mandatory for this group, unlike Instructor Candidates). This will add everyone who responded Yes to the IW registrations list, already marked Confirmed. People who responded No are shown below for visibility but not imported. People already on the list will not be duplicated.

Writes every confirmed registration to the people collection, which attendance.html uses for check-in on course day. People already synced (matched by email) are skipped, never duplicated or overwritten.
