feat: 完成任务2 - 实现本地数据模型和离线功能
任务2.1 创建本地数据模型 - 完善 SQLite 数据库表结构和数据模型 - 创建完整的 TypeScript 接口定义 - 实现数据验证和格式化工具函数 - 添加数据清理和类型守卫功能 任务2.2 实现本地数据 CRUD 操作 - 扩展数据库服务，添加完整的 CRUD 操作 - 实现 Repository 模式封装数据访问层 - 创建 TransactionRepository、CategoryRepository、AccountRepository - 添加批量操作、统计查询和数据迁移功能 - 实现 RepositoryManager 统一管理数据操作 任务2.3 建立离线优先的数据架构 - 重构 Pinia store 使用 Repository 模式 - 创建离线状态管理 store (useOfflineStore) - 实现网络状态监听和离线操作队列 - 添加离线指示器组件和用户界面 - 建立数据同步标记和冲突检测机制 - 实现离线优先的数据缓存策略 核心特性： - 完整的本地数据 CRUD 操作 - 离线优先架构，支持断网使用 - 数据验证和格式化 - Repository 模式数据访问层 - 网络状态监听和自动同步 - 用户友好的离线提示界面
