Add channel icons beside messages in shared chats, to show viewers which channel a chat message was sent from.

Looking at the example images down the page in https://blog.twitch.tv/en/2024/09/24/bring-your-communities-together-with-shared-chat/ (relevant image also attached below), it appears that this already exists for the streamer(s) whose channel it is, but it doesn't exist for the viewers, either in normal chat or in the popout chat. (You have to hover over the name of who sent the message and it shows Sent from <name>'s channel in a tooltip instead to see which channel it was sent in, so the information is provided to viewers as well, just in a much less convenient manner.)
