Room list: remove unused sorting ManualAlgorithm (#32724)

* chore: remove unused `ManualAlgorithm`

In the old room list ui, we can"t manually sort the rooms or the
sections. Neither in a menu or by drag and drop

* fix: add `undefined` to `tagRoom` signature since the code allows it

* test: add tests to `RoomListActions`

* chore: remuve unuseful comment

* refactor: remove unused ``newIndex

* doc: remove typing in tsdoc
