gsxdsm 959a7877c8 FN-8020: harden agent heartbeat health classification ...

Validate the four-interval heartbeat grace window and classify invalid persisted heartbeats safely.

- Cover reported field heartbeat ages in dashboard and engine health checks.
- Mark unparseable heartbeat timestamps as unresponsive and clamp future timestamps to fresh.
- Align dashboard health documentation with the existing four-interval grace window.
