fix(chess): filter own games from live list, dismissable errors, clickable avatars and completed games

- Filter user's own games from public "Live Games" list in lobby
- Fix broken addSpectatingGame filter (playerPubkey is always viewerPubkey)
- Add removeGame() to clean up stale entries when "Game not found"
- Make player avatars clickable to open profile on game screen
- Make completed game cards clickable to view final board state
