fix(apps): 修复通知点击不显示ReminderOverlay和日历编辑后不刷新问题

- AppDelegate: 只存储payload字段而非整个userInfo字典
- LocalNotificationService: 移除旧的取消/稍后提醒action按钮配置
- ReminderNotificationCallbacks: 添加onNotificationPayloadReceived静态回调
- IOSNotificationPayloadBridge: 添加setPendingPayload方法
- main.dart: 设置onNotificationPayloadReceived触发ReminderOverlay显示，添加WidgetsBindingObserver处理后台恢复
- CalendarEventDetailScreen: 编辑保存后正确传递刷新信号给日视图
