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
