/**

* 页面详情
|

*
|
||
* 支持两种入口：
|
||
* 1. GET /api/page/detail?navigationId=4296 → CMS 导航节点（model=page）+ cms_design 内容（旧机制）
|
||
* 2. GET /api/page/detail?path=about → 新版「单页管理」cms_page（按 slug 取已发布单页）
|
||
*
|
||
* 与后端 CmsPageController.getByPath 对应。
|
||
* cms-api 侧已按 status=1（已发布）过滤，未发布/不存在统一返回 data=null。
|
||
*
|
||
* 返回结构（始终为对象，前端用 status 区分）：
|
||
* {
|
||
* status: 'ok' | 'empty' | 'error',
|
||
* pageId, title, path, model,
|
||
* content, layout, photo,
|
||
* keywords, description,
|
||
* hasContent, updateTime, message?
