Fix: Add proper validation for Aster DEX exchange in trader creation

- Add specific field validation for Aster exchange (asterUser, asterSigner, asterPrivateKey)
- Add specific field validation for Hyperliquid exchange (apiKey, hyperliquidWalletAddr)
- Keep existing validation for Binance (apiKey, secretKey)
- Remove debug console logs
- Fix issue where Aster exchange was not appearing in trader creation dropdown

This ensures all three supported exchanges can be properly selected when creating a new AI trader.
