feat(10-08): skeleton tables + BreadcrumbBar + EmptyState in AdminAuditView and AdminUsersView

- AdminAuditView: add BreadcrumbBar (Audit Log, showRoot=false), replace loading spinner with 8-row skeleton tbody, replace empty div with EmptyState (icon=clipboardList) + Clear filters CTA
- AdminUsersView: add BreadcrumbBar (Users, showRoot=false), replace loading spinner with 5-row x 6-col skeleton tbody
- Promote CTA test to use real EmptyState (no stub) so slot content renders
- All 8 skeleton tests pass GREEN
