patch

Apply heartbeatMultiplier to heartbeat unresponsive timeout calculations in HeartbeatMonitor.

When heartbeat speed is slowed (for example heartbeatMultiplier=2), unresponsive detection/recovery and orphaned-running reconciliation now use the correspondingly scaled timeout base, preventing false unresponsive recovery for expected slower cadence. Dashboard health classifier behavior is unchanged.
