feat: auto-mode live strategy — factors when fresh, SMA fallback

- LiveSignal auto-detects factor data freshness (<7 days old)
- Falls back to 1h SMA10/30 (+0.40%/month) when factors are stale
- 30min full factor scan script for discovering new signals
- Ready for 30min factor upgrade when data available
