prlanzarin 001ab9554c video: added voice activity stream sorting, made stream sorting extensible
Video streams can be sorted by voice floor activity in the client according to FreeSWITCH´s floor events. The feature works together with pagination, essentially giving an Last-N like experience while not disrupting too much

Made video stream sorting extensible in a way. The sorting modes for pagination and unbounded can be configured in settings.yml and new sorting modes can be added to the stream sorting util under video-provider. Inline docs explain how to do that

Changed how the stream ID attribute from video-streams collection was passed to downstream components; we had an array map that was executed every change just to map stream to cameraId, which is bizarre. So I changed the cameraId usage in downstream components to be conformat with the collection attributes and shaved off the map where it wasnt needed

Add better selectors to video-list-item container´s VoiceUser fetch
