fix(chat): restore channel assets when leaving shared chat

Browse source 
When a shared chat session ended, the participants' merged emotes and badges
stayed in the channel asset maps, so the other streamer's emote set and badges
kept showing (#522). Only the enter transition was handled.

Detect the leave transition (was shared, no longer shared) and reset: clear the
loaded-participant tracking and re-run getAssets(), which replaces the channel
emote/badge maps with this channel's own assets. Guarded on having actually
loaded shared assets so a flapping source-room-id tag can't cause redundant
refetches.
