Improve "Missing Media" views (Open Meeting Mar 2024)

[rosiel]

Following the "Views" session at the March 2024 open meeting, we realized the Missing Media views were missing filenames in the Data exports, as well they did not use batch processing (but should for scaling).

This PR adds those. And also a missing pager.

Thanks @aOelschlager and team (sorry I forgot who else was in the room and contributing!)

Sorry @rosiel I couldn't get the merge to work in the workspace so I had to use the suggested edit thing instead.
