```

feat(app): 添加本地雷达数据导入功能并完善B-Scan剖面显示

- 新增ImportLocalRadarDialog对话框，支持选择文件夹扫描雷达测线数据
- 在ObjectTreePanel中添加"导入本地雷达数据"菜单选项
- 实现LocalRadarDatasetStore和LocalRadarScanner数据存储和扫描组件
- 扩展DatasetDetailController支持fileUrl参数传递，用于本地文件加载
- 更新ApiDatasetRepository支持雷达数据文件(.data/.iprb/.head/.iprh)解析
- 完善BScanProfileView视图，实现灰度B-Scan图像渲染和通道切换功能
- 添加多通道交错数据读取支持，兼容单文件多通道和多文件单通道模式
- 在数据集列表中存储fileUrl信息，用于本地雷达数据集识别和加载

BREAKING CHANGE: DatasetDetailController.openDataset方法增加fileUrl参数
```
