Normally, generic model views will be spun up through wagtail.admin.viewsets, which takes care of configuring the add_url_name / edit_url_name etc attributes to ensure that they are cross-linked appropriately. But if you're defining one in isolation, that's an unnecessary hoop to jump through, and the error messages if you don't specify them are fairly opaque. Fix this so that:
1. Non-essential cross-links (e.g. the Add button on the index view, and the Delete button on the edit view) are gracefully omitted if the URLs are undefined;
2. Essential cross-links (e.g. the destination of the redirect after a successful form submission) raise an informative error telling the developer what needs to be defined.
Fixes #8190
Django 4 changed the rendering of radio button / checkbox lists to nested divs rather than ul/li - see 5942ab5eb1. This change simply applies the existing li styles to second-level divs.

The ajax-request now uses multipart/form-data, similar to
image-chooser-modal.js/document-chooser-modal.js, which allows to add
and use FileFields in the bulk-upload-views.
If Filter.run is requested to create an unknown output format,
it should not fail silently without writing any output, but instead
throw an exception.
Fixes #8503
