Refactor Detail page to use Destruction List Items endpoint instead of zaken

[Silvia]

At the moment the detail page of a destruction list uses the endpoint /zaken?destruction_list=<uuid> to retrieve the cases in a destruction list.

However, once we start deleting the cases, this don't exist anymore.

Instead, we should use the destruction list items endpoint.

TODO

Backend

• Make the destruction list item endpoint paginated
• Make it possible to filter on destruction list and order on processing status https://github.com/maykinmedia/open-archiefbeheer/pull/268/files
• Expand the details of a zaak (if the zaak exists) #271

Frontend

• Fix problems generated by the changes in the backend
