feat(ui/publish-records): surface 已存草稿 status and client-only manage hint

Render publish_type=draft tasks with the warn tone and 已存草稿 label, swap
the management link copy to 打开草稿箱 for weixin_gzh, and expand the task
summary to mention the publish_authorization_required reason. In the admin
drawer, stop falling back to external_manage_url for missing public links
and instead show a hint pointing operators back to the desktop client for
weixin_gzh / zol records.
