feat: implement real Drift Protocol leveraged trading

- Add /api/trading/execute-drift endpoint for real perpetual trades
- Supports 1x-10x leverage with liquidation risk
- Real stop loss and take profit orders via Drift SDK
- Route leveraged trades (leverage > 1) to Drift instead of simulation
- Update AIAnalysisPanel to use Drift for leveraged positions
- Requires SOLANA_PRIVATE_KEY and Drift account with funds
- Tested with user's 3 USDC collateral for leveraged trading
