feat: Add functionality to handle dummy video streams

This commit adds functionality to handle dummy video streams in the GetStreamGroupLineUp query. Dummy video streams are now identified and processed separately from regular video streams. Dummy video streams are given a unique ID and added to the dummy data collection. This feature will enhance the user experience by allowing the application to handle dummy video streams effectively.
