feat: Library 批量注册 + PeopleView 修复 + 国际化

Library:
- 添加 checkbox 和鼠标框选功能
- Unregistered 卡片添加快速注册按钮
- 状态标签移至左下方，人脸图标移至左侧中间
- Deep Scan 改为 unregister -> register -> process
- 完整国际化（日语、繁体中文、英语）

PeopleView:
- 修复卡片不显示问题（使用 get_file_traces API）
- 移除对 identity_id 字段的依赖

其他:
- 添加日语语言包
- 添加 useDragSelect composable
- 新增文档：Face Bbox Null Bug Report
