fix: AI-calculated SL/TP system with fallback risk management

- Added fallback SL/TP calculation when AI values missing (rate limits)
- Stop loss: 1.5% from entry (scalping-optimized)
- Take profit: 3% from entry (2:1 risk/reward)
- Relaxed API validation to require only stop loss (most critical)
- Disabled problematic import in position-history route
- System now guarantees risk management on every trade

 No more unprotected positions - works with or without AI analysis
