Resolved an issue where some items could be hidden for businesses that are not using the multiple-locations feature.
- Passes, classes, instructors, classrooms, and closures no longer get filtered out by location when multiple locations is turned off, so single-location businesses see everything as expected.
- Turning the multiple-locations feature off now immediately resets all admin views to show every location, instead of waiting for a manual reload.
- Admin pass and staff lists now refresh correctly when you switch locations or toggle the multiple-locations feature.
- Fixed a case where a previously selected location could be lost after reloading.
