📝 docs(story): 更新区域树页面开发文档

- 修改API名称，将`getAreaTree`更新为`getAreaTreeByLevel`
- 移除搜索和筛选功能相关描述，标注其在异步加载架构中无效
- 更新任务状态，标记已完成的子任务
- 调整集成测试范围，移除搜索功能测试项

✨ feat(areas): 实现区域树异步加载页面

- 创建新的AreasTreePage组件，支持省级数据异步加载
- 集成`getAreaTreeByLevel` API获取省级数据
- 添加"新增省"按钮，集成AreaForm组件
- 移除无效的搜索筛选功能及相关UI组件

♻️ refactor(areas): 清理区域树页面代码

- 移除搜索关键词和筛选状态管理
- 删除防抖函数及相关事件处理
- 清理无用导入和未使用的变量
- 优化组件结构，专注于异步树形加载核心功能

 ## Acceptance Criteria
 1. 创建新的 AreasTreePage 组件，专门用于异步加载树形视图
-2. 默认只加载省级节点，使用现有的 `getAreaTree` API 获取省级数据
+2. 默认只加载省级节点，使用现有的 `getAreaTreeByLevel` API 获取省级数据
 3. 页面顶部按钮为"新增省"
-4. 保持现有的搜索和筛选功能
+4. ~~保持现有的搜索和筛选功能~~ (已移除 - 搜索筛选功能在当前异步加载架构中无效)
 5. 验证页面初始加载性能提升
