feat(aiot): ROI配置页面改用cameraCode参数和截图调用

- 路由参数：从query读取cameraCode替代cameraId
- 移除app/stream状态变量，统一使用cameraCode
- 截图调用：getSnapUrl(cameraCode)替代getSnapUrl(app, stream)
- loadCameraOptions：使用cameraCode作为选项value和label
- onCameraSelected：直接设置cameraCode，移除app/stream赋值
- 配置推送/导出：使用cameraCode参数
- 页面标题：显示cameraCode
