Cross-district superadmin visibility (read-only)
A screen for us (not district admins) to see activity across every district and user at once — who's logged in, what's changed, status at a glance — for troubleshooting before support tickets pile up. Explicitly read-only: no editing, no impersonation, no acting on a user's behalf from this screen. If a real change needs to be made for someone (admin or vendor), that goes through a separate, trackable ticket/request flow instead, so there's always an auditable record of who asked for what and why — never a silent superadmin edit. Wanted before the first real district, not post-launch. Worth noting for whoever scopes it: there's currently no per-district RLS boundary at all (B-027 not built yet) — any authenticated admin can already see every district's data — so this view's "visibility" is mostly a UI/aggregation problem today, not an access-control one. The separate on-behalf-of ticket flow, whenever it's built, is a different story and should probably wait for B-027 so it has an actual boundary to route around.
