feat: 完成文件导入功能和Book模型扩展

## 新增功能
- EPUB文件导入功能：支持文件选择、解析和存储
- 文件重复检测：避免重复导入同一文件
- 导入状态反馈：成功/失败消息提示

## 模型扩展
- Book模型新增多作者支持（authors字段）
- 新增章节数统计（chapterCount字段）
- 新增语言标识（language字段）
- 新增EPUB标识符（identifier字段）
- 优化TypeAdapter序列化支持

## 服务优化
- 新增EpubParserService：EPUB文件解析服务
- 改进DatabaseService：错误处理和数据迁移
- 优化BookRepository：调试日志和错误追踪

## 依赖更新
- 新增epubx ^4.0.0：EPUB电子书解析库
- 更新pubspec.lock：同步依赖版本

## UI改进
- AppHeader组件集成完整导入功能
- SafeArea适配：避免系统状态栏重叠
- 优化测试数据结构
