feat(ui:items): uploading an item with a swimlane display

restore the legacy display with new element uploaded, when swimlane is in place
    as the sort is done by server side just add new element in a "new elements" swimlane.
    if user continue to scroll down in cursor/pages and item is found from server,
    UI remove it from the new element and restore the position

    other option: is user refresh it's page, server will restore the natural order
