Enable manual updates for guest phone numbers on Booking.com reservations

Due to Booking.com no longer sharing guest phone numbers via API, hosts are unable to see this critical information in Hospitable. We are requesting the ability to manually add or edit the guest phone number field within the reservation details in Hospitable. This would allow hosts to manually input the number retrieved from the Booking.com extranet, ensuring business operations (such as guest communication and smart lock management) can continue without interruption.
