Redirect Google Vacation Rentals Global Landing Page links to the Hosted Website when one is set

When a host switches the Google Vacation Rentals landing page from the Global Landing Page to a Hosted Website, Google updates its own links. Links saved before the switch, for example by ChatGPT and other AI assistants, still open the Global Landing Page. With no dates passed, it shows "Invalid arrival date / Invalid departure date" and no way to pick dates. We see AI-assistant visitors landing on this error page every week.

Request: when a Hosted Website is set as the landing page, send dateless visits to booking.ownerrez.com/request for that channel to the Hosted Website's property page instead. Or show a date picker in place of the error.
