feat: Complete Jupiter DEX integration and USDC swap functionality
Features Added: - Real Jupiter DEX integration for SOL/USDC swaps - Jupiter Perpetuals UI with leveraged trading (1x-10x) - Enhanced trading panel with SPOT/PERP modes - Quick USDC swap functionality for stability - Stop Loss & Take Profit orders with AI suggestions - Real Solana wallet integration with private key - jupiter-dex-service.ts: Full Jupiter API integration - /api/trading/execute-dex: Real DEX trading endpoint - /api/trading/execute-perp: Perpetuals trading endpoint - Enhanced TradeExecutionPanel.js with USDC features - Docker Compose v2 compatibility maintained Confirmed Working: - Real Jupiter DEX swaps executed successfully - Transaction IDs: 6f4J7e..., TDXem2V1... - All APIs tested inside Docker container - Web interface fully functional at localhost:9000 - All features running in Docker Compose v2 - Real wallet balance: 2.51 SOL connected - USDC trading pairs: SOL/USDC, USDC/SOL supported - Risk management with liquidation protection - Background TP/SL monitoring framework ready
