Replaces the Plan-1 skeleton stubs: OrganizerLayoutV2 now fills
AppShellV2's #sidebar/#topbar/#drawer slots with the ported AppSidebar /
AppTopbar / RightDrawer and sources orgNavItems via useV2Nav() (legal
now that OrganizerLayoutV2.vue is the layouts-v2 zone). AppShellV2 is
unchanged; its contract test stays green. New component test locks the
composition (right component per slot, :groups forwarded, no skeleton).

Tailwind-grid shell skeleton with named slot regions (sidebar, topbar,
default, drawer). OrganizerLayoutV2 wires the skeleton with RouterView,
selectable via definePage meta. Vitest component mount test: 2 tests pass.
