Improved dumpVector, cv::Rect operator<< and exceptions #26602

- Applied format for vector element formatting to ensure consistent and clear output representation.  
- Moved `operator<<` to the `cv` namespace to align with OpenCV's coding standards and improve maintainability.  
- Enhanced error handling by including detailed exception messages using `e.what()` for better debugging.
