In #29209, we introduced a callback to the TableHeaderToggle's parent to update the column order. This commit is to update this component to use that callback.
a3d0a9edbb in core converted the Users route to a native class, which meant that `queryParams` merging no longer works.
Extend it manually in `init()`.
- Adds support for core's customizable user directory: https://meta.discourse.org/t/195263
- Adds a new theme component setting which allows the statistics to be hidden completely from the user cards
- Uses core's new group filter functionality
- Adds .discourse-compatibility so that this component can still be installed successfully on older Discourse versions
