feat: 集成海康威视相机接口

Browse Source 
- 新增 HikvisionCameraController 实现 ICameraController
- CameraFactory 支持 Basler/Hikvision 动态切换（config.json 配置）
- PixelConverter 支持 Bayer RG/GR/GB/BG 8-bit 解码
- 修复采集链断裂问题（finally 中触发下一帧）
- 相机设置面板：宽高和像素格式改为只读显示
- NavigationPropertyPanelViewModel 日志和状态文本改为英文
- 添加 MvCameraControl.Net.dll 到 ExternalLibraries
