refactor(components): 更新标签组件类型定义和数据处理逻辑

- 修改 Tag 接口定义，将 id 和 color 字段改为可选类型
- 更新 onAddTag 回调函数参数类型，从对象改为字符串
- 在 AddTagPopover 组件中添加 useCallback 优化数据获取逻辑
- 调整标签去重逻辑，支持 id 或 name 任一字段匹配
- 更新 DetailHeader 组件的数据类型定义和泛型约束
- 添加 parseMetadata 工具函数用于解析元数据
- 实现 isAnnotationItem 函数判断注释类型数据
- 优化知识库详情页的标签处理和数据类型转换
