Add new event signups to supporter list and sheet

Event signups aren't being added to outreach lists or the roster, delaying volunteer routing. Add each signup to the supporter list and registration sheet so coordinators can act within hours.

Overview

When event signups accumulate without structure, volunteers and donors go unassigned and outreach lags. This workflow ensures each signup lands in your supporter audience and operations sheet so coordinators can begin outreach within hours and avoid missed follow-ups.
