Add select_instances_in_host method to PublisherController and CreateModel

Implemented select_instances_in_host in PublisherController to facilitate instance selection in the host. Enhanced CreateModel with the corresponding method to handle instance selection and focus in DCC, including error handling for selection hooks. Updated OverviewWidget to connect double-click events to the new instance selection functionality while preserving existing behavior.
