Add signal quality version comparison to analytics dashboard
- Created /api/analytics/version-comparison endpoint
- Shows performance metrics for v1, v2, v3 scoring logic
- Compares: trade count, win rate, P&L, quality scores, MFE/MAE
- Special focus on extreme positions (< 15% or > 85% range)
- Tracks weak ADX count (< 18) for each version
- Visual indicators for current version (v3)
- Data collection progress notice for v3 (need 20+ trades)
- Legend explaining MFE, MAE, extreme positions, weak ADX
Enables data-driven optimization by comparing algorithm performance
with clean, version-tagged datasets.
