Add program registrations to the central roster sheet

You miss prep when registrations only exist in the registration portal and aren't in your roster. The roster updates automatically so coordinators get a complete attendee list within minutes.

Overview

Registrations that only live in the registration portal leave coordinators scrambling for attendance lists and billing details. This flow writes every new registration into a central roster so coordinators and billing staff have a complete attendee list within minutes. That reduces day-of chaos and gets invoices and reports ready ahead of sessions.
