Reschedule and cancel inside customer accounts

Customers can now reschedule and cancel a booking without leaving their Shopify customer account. It works on the My Bookings page and from the order status page. Both previously sent the customer out to a separate page on your storefront partway through. The times offered respect the event's working hours, lead time, blackout dates and staff availability, and availability is checked again when the customer confirms. Whether customers can reschedule or cancel at all is still controlled per event, as before.
