Update ride-along roster and alert crew on cancellations

Your ride-along emails hide cancellations, leaving the training roster out of date and crews unsure who will attend. The roster is updated and duty crews are notified the same day.

Overview

Cancellations hidden in inbox threads create confusion and last-minute staffing gaps for training and duty shifts. This flow extracts cancellation details, updates the central roster, and notifies duty crews so coordinators see changes within minutes and avoid same-day gaps.
