[FIX] website_event_track_[session|live]: adjust event 'Youtube' layouts

This commit makes some minor changes to the Youtube video & chat layouts when
embedded in an event to ensure a better viewing experience.

Changes in details:
- Improve the "chat tab" to ensure the width is sufficient to display all of
  the Youtube chat iframe on any resolution ;
- If the video is "live" and has a chat tab, the chat is now displayed as the
  first tab (before this change, the "other tracks" tab was always displayed
  first) ;
- When displaying the next suggestion, add a covering block to avoid a
  potential flicker while fetching the suggestion to go to.
