fix(forum): align forum pages with the reference layout

- cards: restore the shared card shell, add author follow/message actions,
  score group, last-reply meta and reference plate header actions
- home: desktop left tab rail, widget-only sidebar, reference load-more markup
- plate: 1-based tabs, reference defaults (全部/推荐/最新回复/热门/精华)
- post: fixed action rail, score footer, author card, h1 article title
- quick publish: plate selector moved into the submit row like the reference
