fix: don't trigger scale-down if already at min replicas

Browse Source 
checkAndScale was deciding to scale-down based on avgLoad without checking
if already at minimum replicas. This caused unnecessary scale-down attempts
that would fail and log noise.

Add check: only scale-down if instances.size > scaleMinReplicas
