Adds AdminApp as a lazy-loaded route subtree in App.tsx, mounting ProtectedRoute, AdminLogin, AdminLayout, and all five CRUD pages built in Tasks 3-11. Mounted as a sibling of the public Layout route (not nested under it), since the admin panel has its own AdminLayout sidebar rather than the public nav/footer. Manually verified end-to-end against the local Supabase stack: sign-in redirect guard, all five pages rendering real seeded data, creating and cancelling a real booking through the UI (confirming the booked_slots cleanup trigger from the merged Phase 2A follow-up fixes correctly frees the slot), and sign-out. No console errors across the flow. Claude-Session: https://claude.ai/code/session_01NhxA4npAXAxmCDEJt6kxSH
