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

+
+## 小程序分享 / 朋友圈能力全量接入
+- 新增 `src/hooks/useShare.ts`：统一注册 `useShareAppMessage` + `useShareTimeline`，自动追加 `inviter=${user.id}` 裂变参数；导出 `isTimelineSinglePage()`（scene===1154）。
+- 新增 `src/components/SharePoster/index.tsx`：Canvas 2D 生成「封面+标题+价格+小程序码」海报，返回临时图路径作 imageUrl。
+- 新增 `src/api/share.ts`：`generateShareCode(page, inviterId)`，复用 `generateMiniProgramCode`（scene=uid_${id}，page 透传）。
+- 扩展 `src/api/shop/shopInvite/index.ts` 的 `generateMiniProgramCode`，URL 透传 `page` 参数（后端需读取转发）。
+- 接入 10 个页面：商品/积分/拼团/秒杀/活动/赛事详情（带 canvas 海报）；邀请下级/分销推广/升级VIP/分享赚佣金（仅 enableShare + useShare）。
+- 类型检查：本次改动零错误，仅余 1 个历史既有错误（TS2688 @tarojs/taro 类型解析，非本次引入）。
+- 待办/注意：朋友圈分享必须真机测试；后端需支持按 page 生成指定落地页小程序码；单页模式降级（避免强制登录跳转）可调用 `isTimelineSinglePage()`。

 - 字段：订单号(`character_string1`)、商品名称(`thing4`)、联系人(`thing10`)、联系电话(`phone_number7`)、送货地址(`thing8`)

+## 分享 / 朋友圈能力（2026-07-13 接入）
+- 统一封装：`src/hooks/useShare.ts`（`useShare({title, path?, query?, imageUrl?})`，内部一次注册 `useShareAppMessage` + `useShareTimeline`，并自动在 path/query 追加 `inviter=${当前用户id}` 做裂变归因；`isTimelineSinglePage()` 判断朋友圈单页模式 scene===1154）
+- 海报组件：`src/components/SharePoster/index.tsx`（Canvas 2D 绘制封面+标题+价格+小程序码，返回临时图路径作 imageUrl）
+- 小程序码接口：`src/api/share.ts` `generateShareCode(page, inviterId)` 复用 `generateMiniProgramCode`（scene 用 `uid_${inviterId}`，page 透传但后端需读取转发才生效）
+- 裂变约定：分享链接 query 用 `inviter`，与 `src/utils/invite.ts` 的 `parseInviteParams` 读取字段一致
+- 已接入页面：商品详情、积分商品、拼团、秒杀、活动、赛事（带 canvas 海报）；邀请下级、分销推广、升级VIP、分享赚佣金（仅 enableShare + useShare，无海报）
+- 注意：tabBar 4 页（首页/分类/订单/我的）不支持朋友圈分享；朋友圈分享必须真机测试（开发者工具无预览）
