The refactor from integration-based to option-based config changed the
useQuery enabled condition from 'integrationIds.length > 0' (always true
when an integration was linked) to 'query.length > 0'. The combination
of the debounced search value and the enabled toggle inside the nested
useOptions callback caused the query to never fire, making stations
unsearchable in the edit form.
Removing the enabled guard lets the query always run. The 300ms debounce
already prevents excessive requests.
