feat(appointment): expire pending bookings past their payment window

Add findPaymentExpired (pending with expires_at < now) and have the
cancel-expired command flip both payment-expired and slot-time-passed
pendings to expired (deduped). Run it on a schedule (e.g. every minute:
* * * * * php bin/console app:cancel-expired-appointments) to free locks
held by unpaid bookings.
