Subject: [PATCH] Invalidate the router on sign out so account orders clear
 immediately

Signing out only clears the auth session cookie; a route already
loaded (e.g. /orders) keeps its stale loader data until something
triggers a reload. Call router.invalidate() once signOut succeeds so
the current route's loader reruns against the now-signed-out session.
