provides a default route to handle 404 response in prod mode

The factory was listing all the existing endpoints if no route was
found for a request. By defining this new route, which match all
kind of request, we will bypass the `RestxMainRouterFactory`.
This route is only activated in "prod" mode, as the listing might
be useful during development.
