Attendees panel in Modern Express client now displays pagination

In this update, the Attendees panel in Modern Express client has been enhanced to display pagination when the number of attendees with video is large. The page size is responsive and equal to the number of cards on the screen.

The panel now displays the total number of attendees in the fixed header and the pagination toolbar in the fixed footer. Scrolling is not supported. Users can navigate the pages horizontally.

Only the active video channels that are viewable are displayed in the client. This allows the Modern Express clients to indicate a set of channels they would like to watch and only receive the video streams for their watched channels. This capability along with pagination helps conserve bandwidth and improves the overall user experience in the Modern Express client.
