ref(routes): replace stats nav-v2 redirect with route-level redirects

The navigation-sidebar-v2 feature flag is now fully launched, so the
OrganizationStatsWrapper component and its useRedirectNavigationV2Routes
hook are no longer needed. Replace with declarative redirectTo entries
in the route definitions, pointing /stats/* to /settings/stats/*.
