[Server] Add extension points for tournament game commands

Adds the server-side seams the tournament engine will plug into:
- Dispatch ReportMatchResult / AdvanceTournament /
  TournamentSettingsSelect in processGameCommand; base implementations
  return RespContextError so regular games reject them safely
- Server_AbstractPlayer::setDeck lets a backend install a deck into a
  player slot directly
- Server_Room::getUserInterfaceByName resolves a room user by name for
  automated game setup
