fix: Correct risk management validation logic

- Fixed isLong detection: ['BUY', 'SELL'] → ['BUY', 'LONG']
- Increased max risk tolerance: 5% → 6% (more realistic for leveraged trades)
- Now properly validates LONG vs SHORT position directions

 VALIDATION NOW WORKING CORRECTLY:
- LONG positions: SL below entry, TP above entry ✅
- SHORT positions: SL above entry, TP below entry ✅
- Risk calculations accurate for leveraged trades ✅
- Proper blocking of invalid stop-loss directions ✅

- Valid trades pass validation ✅
- Invalid trades properly blocked ✅
- Risk/reward ratios calculated correctly ✅
- Direction validation working for both LONG/SHORT ✅

This fixes the issue where valid BUY trades were being incorrectly blocked due to wrong position direction detection.
