1. В компоненте TradingCup  запрашивается cup из useRustWsServer, сделать отрисовку канвас как в методах renderTrade renderTrades .
2. renderTrade renderTrades то другой  немного компонент с немного другими данными, нужно использовать его в TradingCup  только с нашими данными type CupItem = {
  futures_price_micro: number;
  quantity: number;
  spot_quantity: number;
  side: string;
};

3. В методе renderTrade() показатели quantity и price_float перемножаются, чтобы получить объем в $. Нам это не нужно, будем выводить только quantity.
Нужно все отрисовать в канвасе И использовать тоже самое соединение, что установлено в rustWsServer.ts 
обязательно везде typescript. Напиши весь код что и как где делать
