feat: Implement Hybrid 60/40 scoring approach for Enhanced Signal Scoring

PROBLEM:
- Enhanced Score alone (67.8%) was blocking trades with high Base Confidence (97.5%)
- Low Volume Score (40/100) was dragging down the total
- Good trading setups were being rejected

SOLUTION: Hybrid 60/40 Approach
- Final Score = (Base Confidence × 60%) + (Enhanced Score × 40%)
- The proven trend analysis system keeps primary weight (60%)
- Enhanced scoring still filters bad setups (40%)

EXAMPLE:
- Base Confidence: 97.5%
- Enhanced Score: 67.8%
- OLD: final = 67.8% (blocked at 70% threshold)
- NEW: final = (97.5 × 0.6) + (67.8 × 0.4) = 85.6% (passes!)

BENEFITS:
- Respects the proven base trend system
- Enhanced scoring still adds value
- Fewer false rejections of good trades
- Better balance between filtering and opportunity
