- We have already aggregated open abuse reports by
reported-user & category for the list view in
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/119282.
- In this MR, we will display the same aggregated reports in the
detail view of an abuse report, so admins can see all the
reported content in one place.
- Add index on abuse_reports(user_id, status, category)

Changelog: added
