- FIX A (IMPORTANT): PrimeVue Breadcrumb ignores `route` key; map non-last
items with `command: () => router.push(item.to)` for real client-side nav
- FIX B: add type="button" to all 6 native <button> chrome elements
- FIX C: authStore.logout() bare call matches project no-void pattern
- FIX D: document param-route edge case in toBreadcrumbItems
- FIX E: regression test asserts command+push on non-last, no command on last,
no `route` key on any item

- useBreadcrumb composable: pure toBreadcrumbItems() helper + thin
useRoute() wrapper; route-driven, no prop coupling
- AppTopbar: hamburger→setMobileOpen, theme/density toggles→shell store,
PrimeVue Breadcrumb/OverlayBadge/Popover/Avatar/Menu; replaces all
manual document.mousedown listeners with PrimeVue built-in dismissal;
notifications stubbed (useNotificationStore is a toast queue, not a
feed — TODO TECH-WS-GUI-REDESIGN); sign-out→authStore.logout()
- Unit tests: 10 breadcrumb + 6 AppTopbar assertions (16 total, all pass)
