Adds a dropdown menu (MoreVertical icon) to the Todo column header with a
Respecify All action that bulk-moves every visible todo task back to Triage
after a confirm dialog. Toasts surface partial-failure counts when the
parallel onMoveTask calls don't all succeed. Click-outside and Escape close
the popover. Supporting .column-menu / .column-menu-popover / .column-menu-item
styles added in styles.css.
