feat(ui): open list items counter on Listen, none on Workspace

New stat listItemsOpenCount: unchecked items in all lists the user sees
(own, shared directly or through a group), shown as accent counter on
Listen in the header and the mobile bottom bar. Workspace loses its
counter. Stats refresh on list events and after deleting an item.
