==== Technical background
Since {T363358}, MediaWiki core has parent classes for building pages that display lists of contributions: `ContributionsSpecialPage` and `ContributionsPager`. These are currently used to make Special:Contributions, Special:DeletedContributions and (in CheckUser) Special:IPContributions.
For Special:GlobalContributions, we will need `SpecialGlobalContributions` and `GlobalContributionsPager`. This will work similarly to Special:IPContributions in normal (non-archive) mode. Since it needs to use the CheckUser tables, it will only show contributions from the last 90 days.
This task is for creating the pager (which fetches the results and displays them).
==== Acceptance criteria
* Submitting the form with an IP address or range fetches the latest revisions from temporary accounts using those IP addresses for all wikis in this wiki farm (limit to 20 per wiki)`GlobalContributionsPager` is implemented, extending `ContributionsPager`
* `GlobalContributionsPager::doQuery` logs access, similar to`IPContributionsPager`
* Pending final designs,`GlobalContributionsPager::getRevisionQuery` is overridden to fetch the latest contributions by temporary accounts from a given IP or range. It makes use of the `cuci_temp_edit` table and possibly other optimizations discussed in {T355672}. results are displayed in a paginated list and sorted by descending timestampThis is the bulk of the work for this task.
