Accept/Decline Bookings in Checkpoint Status

Currently, when a booking is in 'Checkpoint' status (awaiting guest identity verification on the OTA), the option to accept or decline the request is not available within Hospitable. This requires hosts to manually switch to the OTA platform (e.g., Airbnb) to manage these requests.

The goal is to bring the same functionality to Hospitable, allowing hosts to accept or decline these bookings directly from the Hospitable interface.
