fix: reduce loop interval to 1s and add heartbeat logging

- Loop sleep 30s → 1s to never miss the 4-second TimeframeSync window
- Data polling remains at 30s intervals via monotonic timer
- Force poll before signal check to ensure fresh data
- Add [Heartbeat] log every 15m with Meta/ATR/Close/Position
- HOLD reasons now logged at INFO level (was DEBUG)
