When filtering by multiple inspector teams, show only inspectors in all selected teams

Users want the calendar (or scheduler) team filter to show only inspectors who belong to all of the selected teams—for example, when they select both “pool” and “crawl space,” the list should show only inspectors who are on both teams, not everyone in either team. That way schedulers can quickly find people who can do the full set of services needed for a job.

Why it matters: Schedulers need to match inspectors to jobs that require multiple capabilities; showing the intersection of selected teams avoids showing people who can’t do part of the work.
