Docs: Complete exchange configuration documentation

Update configuration documentation across all 4 languages (Chinese, English,
Russian, Ukrainian) with comprehensive exchange-related fields:

Configuration field table updates:
- Add `exchange` field (binance/hyperliquid/aster)
- Add `hyperliquid_private_key` field with 0x prefix warning
- Add `hyperliquid_wallet_addr` field
- Add `hyperliquid_testnet` field (optional, defaults to false)
- Update `ai_model` to include "custom" option
- Change Binance API key fields to show conditional requirement
  (only required when using Binance exchange)

config.json.example updates:
- Add `enabled` field to all trader configurations
- Set appropriate enabled states for example traders
- Ensure all traders have exchange field properly configured

This makes it clear to users which configuration fields are required
for each exchange option (Binance, Hyperliquid, or Aster DEX).
