feat: Complete Trading Bot v4 with Drift Protocol integration

Features:
- Autonomous trading system with Drift Protocol on Solana
- Real-time position monitoring with Pyth price feeds
- Dynamic stop-loss and take-profit management
- n8n workflow integration for TradingView signals
- Beautiful web UI for settings management
- REST API for trade execution and monitoring

- Next.js 15 with standalone output mode
- TypeScript with strict typing
- Docker containerization with multi-stage builds
- PostgreSQL database for trade history
- Singleton pattern for Drift client connection pooling
- BN.js for BigNumber handling (Drift SDK requirement)

- Configurable stop-loss and take-profit levels
- Breakeven trigger and profit locking
- Daily loss limits and trade cooldowns
- Slippage tolerance controls
- DRY_RUN mode for safe testing

- Real-time risk calculator
- Interactive sliders for all parameters
- Live preview of trade outcomes
- Position sizing and leverage controls
- Beautiful gradient design with Tailwind CSS

- POST /api/trading/execute - Execute trades
- POST /api/trading/close - Close positions
- GET /api/trading/positions - Monitor active trades
- GET /api/trading/check-risk - Validate trade signals
- GET /api/settings - View configuration
- POST /api/settings - Update configuration

- Fixed Borsh serialization errors (simplified order params)
- Resolved RPC rate limiting with singleton pattern
- Fixed BigInt vs BN type mismatches
- Corrected order execution flow
- Improved position state management

- Complete setup guides
- Docker deployment instructions
- n8n workflow configuration
- API reference documentation
- Risk management guidelines

- Runs on port 3001 (external), 3000 (internal)
- Uses Helius RPC for optimal performance
- Production-ready with error handling
- Health monitoring and logging
