Entity usage list does not scale

Problem/Motivation

We have an entity with *a lot* of usages. 56 pages of them.

Because entity usage currently loads all the usages and then only pages them in the UI, that is super slow and uses a ton of resources.

Proposed resolution

Find a way to do paging in the query. I still believe it would make sense to group usages per entity which might or might not make that easier :)

Remaining tasks

User interface changes

API changes

Data model changes
