Handle wheelForce <= 1 in auto target calc

Add a guard in ConvertAutoMarginToAutoTarget to return wheelForce when wheelForce <= 1f to avoid clamping with min > max (which could throw an ArgumentException). Update comment to clarify that an unconfigured or very small wheel force has no meaningful target and should be returned as-is. This prevents crashes for contexts where wheelForce is below 1 Nm.
