Automatic Cancellation of Reservations After Payment Grace Period Expires

Problem: Currently, when a Direct booking's payment grace period expires without payment, the reservation remains in 'awaiting_payment' status and continues to block the calendar indefinitely.

Current Workaround: The host must manually monitor these reservations and cancel them one by one to free up the dates.

Impact: This creates additional operational overhead for hosts and risks losing potential bookings because dates remain blocked by unpaid reservations.

Proposed Solution: Implement a system where reservations are automatically cancelled once the configured payment grace period has elapsed without a successful payment.

Unlock: Hosts will have their calendars automatically cleaned of unpaid bookings, ensuring maximum availability without manual intervention.
