Collapse Nest summary by default; tap title to expand

Move the LIVE chip and listener count out of the header strip and into
the right side of the Stage card's title row (listeners first, then
chip). The remaining summary now hides by default and toggles when the
user taps the room title in the top bar, reclaiming vertical space for
the stage and chat.
