Fix/visuals (#469)

* Geohash peers: show face.dashed for self when channel selected via teleport; face.smiling otherwise

* Geo presence: broadcast 'teleport' tag on geochat join; track teleported participants and show face.dashed for them in peer list

* Teleport tag: attach to actual geohash chat events (sendMessage, emotes, screenshots) instead of separate presence; remove presence emit

* Fix: show face.dashed for any teleported peer (not just self) in geohash list

* Geo list: show self immediately on channel switch and mark teleported state; clear teleported flags on leaving geochat

* Teleport persistence: recompute teleported based on current location vs selected geohash; add face.dashed icon to Teleport button label

* Styling: use lighter green/orange for #abcd suffix after nicknames in all chats (senders and @mentions)

* Peer lists: render #abcd suffix as lighter green/orange (self orange) in geohash and mesh lists

* Toolbar: move unread icon next to #channel badge and allow dynamic width; Peer lists: increase top spacing before first item

* Toolbar: prevent geohash channel badge from truncating; give it layout priority and fixed width

* Toolbar: make unread envelope independent from channel button (sits left of badge); fix accidental taps opening channel selector

* Toolbar: make unread envelope open most recent unread/private chat directly

* Geohash peer list: render self row fully orange (icon, base, suffix, '(you)')
