Cancel a run of fake bookings

1. Find the number in Clients and open their page.
2. Under Cancel all of their upcoming bookings, press the cancel button and confirm.

Their upcoming bookings are cancelled, and the times free up. They aren't messaged. It can't be undone in one go: you'd restore each booking yourself.

To stop it happening again, limit how many bookings one number can have. (Limit bookings per phone number)
