We shouldn't care about the ordering here; if we did, it would be more
appropriate to use `take` or `first`. Having the ordering can result in
the database picking a bad query plan, as it might think sorting the
whole table first is the best option.
We're filtering the events using `Event#visible_to_user?`.
At most we're loading 100 events at once.
Pagination is also dealt with in the finder, but the resulting array
is wrapped in a `Kaminari.paginate_array` so the API's pagination
helpers keep working. We're passing the total count into that
paginatable array, which would include confidential events. But we're
not disclosing anything.
