Subject: [PATCH] =?UTF-8?q?feat(ui):=20handle=20PresenceList=20in=20lobby?=

The lobby now populates from PresenceList signal events:
- Relay broadcasts user list on register/deregister
- JS receives "presence_list" signal-event
- Updates lobbyUsers map (excluding self)
- Renders user rows with identicon, name, fingerprint

Users appear in the lobby as soon as they register their
signal channel — no need to join voice first.
