Subject: [PATCH] fix(admin): use FA5 long-arrow icons in post list sort
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

后台文章列表的排序箭头还停留在 FA4 的 fa fa-long-arrow-down / up，而且类名是字符串拼接出来的。契约测试按完整的 fa fas fa-* token 逐个校验，看不穿拼接后的类名，所以这条一直是漏网之鱼。

改为按升降序直接输出完整的 fa fas fa-long-arrow-alt-down / fa-long-arrow-alt-up 两个字面量，走全局 FA5+ 图标系统。

验证：node --test tests/**/*.test.cjs 全量 572 项通过；php -l src/Admin/Native/PostListEnhance.php 无语法错误。
