fix(rectification): simplify delivery card and guard double turns (BUG-595, BUG-596)

Make the range card row-select, drop the composer 先这样 control and adopt status bar, keep delivery copy to three sentences with a folded verification report, and skip a second no-message agent run after a terminal delivery turn.
