Fix Drift trading execution: leverage, stop loss, and take profit
- Fix leverage application in trade execution (was not being applied) - Fix stop loss orders with proper OrderTriggerCondition.BELOW/ABOVE - Fix take profit orders with TRIGGER_LIMIT order type - Add OrderTriggerCondition import from Drift SDK - Increase minimum stop loss from 0.5% to 3% to prevent cancellation - Improve error logging for stop loss placement failures - Add comprehensive risk management parameter validation - Update order placement logic with proper trigger conditions All trading functionality now working: Leverage application (2x, 5x, etc) Stop loss orders (minimum 3% for stability) Take profit orders (minimum 1%) Account balance calculations Progress tracking and UI enhancements
