feat: implement strategy-aware analysis intervals and remove manual leverage controls

- Remove manual leverage field from automation v2 page since AI now handles leverage automatically
- Fix scalping strategy analysis intervals from 60 minutes to 2 minutes for proper high-frequency trading
- Implement intelligent interval detection based on selected timeframes:
  * Scalping: 2 minutes (5m, 3m, or multiple short timeframes)
  * Day trading: 5 minutes (1h, 2h timeframes)
  * Swing trading: 15 minutes (4h, daily timeframes)
- Fix Drift SDK API calls: replace getTotalPerpPositionValue() with getFreeCollateral()
- Clean up UI by removing manual controls since AI systems handle optimization
- Fix syntax errors in automation service and balance API
- Ensure proper margin calculations using correct Drift Protocol methods

Tested: Scalping strategy now correctly analyzes every 2 minutes instead of 60 minutes
