Subject: [PATCH] feat: add indicatorVersion tracking to backend

Added indicatorVersion field to track which TradingView indicator version
generated each signal (v5, v6, etc.)

Changes:
- Updated ExecuteTradeRequest interface to include indicatorVersion field
- Added indicatorVersion to both createTrade() calls with default 'v5' fallback
- Field already exists in Prisma schema (indicatorVersion String?)
- Defaults to 'v5' for backward compatibility with old alerts

This enables comparison of indicator performance:
- v5: Original Money Line indicator
- v6: Improved version with 100-bar price position filter

Works alongside existing signalQualityVersion (v4) which tracks backend
scoring algorithm changes. Two separate version fields:
1. indicatorVersion = TradingView Pine Script version (v5/v6)
2. signalQualityVersion = Backend scoring logic version (v4)

Frontend can now filter/compare trades by indicator version in analytics.
