feat: Realistic backtesting with OHLCV data and spread costs

Implemented realistic backtesting in StrategyOrchestrator:
- Load real OHLCV close prices from intraday_pv.h5
- Calculate real price returns (pct_change)
- Apply signal positions to real returns
- Include spread costs (1.5 bps per trade)
- Fallback to factor proxy if OHLCV unavailable

Strategies now evaluated with actual market conditions.
