P5-18: PresenceRingAvatar wrapper component applies a 2px box-shadow
ring to user avatars — green (online), yellow (idle/unavailable), red
(DND via status_msg='dnd'), no ring (offline). Applied to: message
timeline sender avatars, members drawer (members + knock requests),
@mention autocomplete, and inbox notification senders.
P5-6: Leading emoji in room names renders at 1.15× in the sidebar via
Unicode emoji regex detection in RoomNavItem. Emoji picker (EmojiBoard
in PopOut) added to all three room-name inputs: Create Room dialog
(converted to controlled input), Room Settings name field (shown only
when canEditName), and the "Rename for me" local rename dialog.
