Stream Detail: As a failsafe, try and play a stream even if it reports as idle

Currently our dashboard doesn't even attempt to play back a stream if the API reports that the stream is idle. Obviously we want to fix that field, but in the meantime a stream could be completely functional behind the scenes and we just wouldn't show it to the user. As a failsafe mechanism, I'd propose that the player should always attempt to play the stream in the background even if the stream reports that it's idle.

Start by locating the dashboard's Stream Detail playback logic and the condition that prevents playback when the API reports a stream as idle. Verify the behavior with an idle-reported stream that is functional behind the scenes, and consider the work done when the player attempts playback regardless of that status.
