⚡️(frontend) narrow chat participant list update events

Browse Source 
Reduce the set of events that trigger an update of the participant
list in the chat, keeping only those relevant to display: attribute
and name changes.

This avoids unnecessary re-renders when other, unrelated participant
events fire.
