feat(user): 使用微信原生 Picker 替换所在地选择弹层

- 删除 NutUI Address 相关导入、状态及地区数据转换逻辑
- 新增派生 regionValue 用于绑定微信原生 Picker 的 value
- 将 handleRegionChange 调整为处理微信 Picker 的事件
- 将所在地选择 UI 修改为微信原生 Picker 包裹的视图结构
- 地图定位失败使用弹窗提示，引导用户手动选择或重试
- 移除手动打开地区选择器的函数及 NutUI 组件
- 保留 RegionData 用于文本智能识别解析
- 编译通过，提升在无地图或无权限环境下的地区选择稳定性
