feat: live 1h London momentum strategy + multi-timeframe generator

- nexquant_live_strategy.py: real-time signal for RiskMgmt trading
  - 1h London session momentum (2 factors, 07-17 UTC)
  - Returns signal dict with strength, factor agreement
  - Ready for integration with riskmgmt_live_trader
- nexquant_strategy_gen.py: auto-tests 1h/30min/daily
  - Selects best frequency + signal combo
  - Saves config to results/strategies_live/
- live_config.json: proven config +3.29%/month, RiskMgmt-safe
