feat(miniprogram): 初始化 Taro 4 + React 小程序项目

- 手动创建 Taro 4.2 + React 18 + TypeScript 项目骨架
- 配置 webpack5 编译、SCSS 样式、医疗清新主题
- 实现 API 请求层（JWT 自动注入 + token 刷新）
- 实现 auth store（微信登录 + 手机号绑定 + 就诊人管理）
- 实现登录页（微信一键登录 + 手机号授权绑定）
- 实现首页（问候栏 + 今日健康卡片 + 快捷服务 + 即将到来）
- 实现我的页面（个人信息 + 功能菜单 + 退出登录）
- 健康/预约/资讯占位页
- TabBar 5 个入口：首页/健康/预约/资讯/我的
