richarjiang 25b8e45af8 feat(medications): 实现完整的用药管理功能
添加了药物管理的核心功能,包括:
- 药物列表展示和状态管理
- 添加新药物的完整流程
- 服药记录的创建和状态更新
- 药物管理界面,支持激活/停用操作
- Redux状态管理和API服务层
- 相关类型定义和辅助函数

主要文件:
- app/(tabs)/medications.tsx - 主界面,集成Redux数据
- app/medications/add-medication.tsx - 添加药物流程
- app/medications/manage-medications.tsx - 药物管理界面
- store/medicationsSlice.ts - Redux状态管理
- services/medications.ts - API服务层
- types/medication.ts - 类型定义
