refactor(frontend): migrate app layer and auth to FSD

- Create app/ layer: App.tsx, providers, routing, layouts
- Create entities/session/ for auth domain
- Extract SessionProvider + AppProviders composition
- Add ProtectedRoute, AppRoutes to app/routing/
- Add AppLayout to app/layouts/
- Convert legacy files to re-export shims
- Update Login/Register/Profile pages to useSession
