Add routing foundation to compliance-portal

Wire up react-router with a root layout route and an index home page,
following the single-arborescence conventions: pages live under pages/,
routes are built from AppRoute via routeFromAppRoute, and route bundles
load lazily behind a Suspense fallback.

Add the @probo/routes and @probo/react-lazy workspace dependencies that
the route setup relies on.
