When a meeting whose scheduled time is already in the past gets cancelled in the system, Chili Piper still sends a cancellation email to attendees. Recipients are confused to receive a cancellation notice for a meeting that already happened.

Requested behavior: don't send (or let admins suppress) cancellation emails when the meeting's scheduled time has already passed.

Why it matters: cancellation notices for past meetings confuse merchants and partners and undermine trust in the booking communications
