feat(ios): 添加用药计划Widget小组件支持

- 创建medicineExtension小组件，支持iOS桌面显示用药计划
- 实现App Group数据共享机制，支持主应用与小组件数据同步
- 添加AppGroupUserDefaultsManager原生模块，提供跨应用数据访问能力
- 添加WidgetManager和WidgetCenterHelper，实现小组件刷新控制
- 在medications页面和Redux store中集成小组件数据同步逻辑
- 支持实时同步今日用药状态（待服用/已服用/已错过）到小组件
- 配置App Group entitlements (group.com.anonymous.digitalpilates)
- 更新Xcode项目配置，添加WidgetKit和SwiftUI框架支持
