TODO / Allow creating new pages under scope on web

This casually started working without us noticing much after 3f4e7594ea5d28c3b30a0b7e874ca4627849cbea made parent selection a bit more accurate for scopes. Hurray.

We likely just have to set the path: API argument based on the has scope status of the parent article.

As of the commit that adds this line, it should likely be possible to do it on the backend. On the frontend however we convert / to - so it doesn't work on the existence checks. We need a more accurate ID conversion there.
