See multiple participants on stage
Pin and unpin to stage
Automatic selection of participants to be displayed on the stage filmstrip based on dominant speaker changes
Make Filmstrip a reusable component. Used by MainFilmstrip (old functionality) and the new StageFilmstrip
Rename DominantSpeakerName to StageParticipantNameLabel
Active border now showed only for the dominant speaker (no longer for the pinned participant)
Hide video from the vertical filmstrip for the participants on stage
Update video constraints
Updated pinned indicator

The Dominant speaker name badge was overlaping the shared video
controls  (audio level, play/pause, etc).

Move label to LargeVideo so that's it's centred in the view instead of the whole screen
Move vertical filmstrip max width calculation to a function and use it to set the large video width

In large view. This aligns the behavior with the web.
