feat: /api/resources/list 后端组树返回 — TreeUtils.buildTree + sort

- ResourceNode 新增 children 字段
- listAll() 改用 TreeUtils.buildTree 组树，按 sort 排序
- 前端无需自行组树，直接渲染 data
- 测试适配树结构，前端文档同步更新

 ### 6.3 前端开发建议
 
-1. **树形组件**：推荐使用 `parentId` 在前端组树，后端返回扁平数组性能更好
+1. **树形数据**：后端已组好树并按 sort 排序，前端直接渲染 `data` 即可，无需自行组树
 2. **表单提交**：使用 `URLSearchParams` 或 `qs` 库构造表单字段，不要用 `JSON.stringify` 整体打包
 3. **ID 处理**：所有 id 字段按字符串处理，不要 `parseInt` / `Number()`
 4. **表单校验**：根据节点类型动态显示必填字段
