Support Booking.com “shared home / private room” property type with “shared bathroom”

Support Booking.com “shared home / private room” property type + “shared bathroom” configuration for PMS-connected listings, so hosts can accurately represent accommodations without the setting reverting after sync. Current behavior: Host updates property type/bathroom in Booking.com Extranet, but it reverts (likely due to unsupported values through the channel manager/API). Impact: Guests misunderstand the accommodation type, leading to confusion and manual clarification messages.
