Automatic notification for inactive customer (not trained X times)

Send a notification to the coach (and optionally the client) when a member has missed X training sessions/bookings or has not trained for Y days. Configurable per company/event type: threshold (X/Y), which events count (PT/group class/open gym), whether “no-shows” and/or “no bookings” count, channel (in-app/email), and an overview of “inactive members” in the dashboard.
