Add private chat feature and fix peer discovery issues

- Implement 1:1 private messaging with IRC-style interface
- Add private message type to protocol with routing through mesh
- Show orange notification dot for unread private messages
- Fix peer list not showing connected peers
- Update peer nicknames immediately on first message
- Auto-exit private chat when peer disconnects
- Improve join/leave channel messages visibility
- Make send button larger for better UX
- Center and color private chat header in orange
