Fix StayHostingDetailsQuery timeout crashing get_reservations

ReadTimeout was caught by the TransportError handler in _gql and re-raised
as AirbnbAuthError, causing the whole airbnb service to be skipped on diff.

Fix: separate TimeoutException from TransportError in _gql so timeouts don't
masquerade as auth failures. In fetch_details, catch timeout per-reservation
and log a warning + return a null tuple (filtered by the existing if ci and co
guard) so one slow detail call can't abort the full reservation list.

Also add a Semaphore(3) so detail fetches don't all fire simultaneously.
