Gets the minimum and maximum vector magnitude (√(dx²+dy²)) across all data points.

On a full data update the range is computed inline during the magnitude cache pass — no extra sqrt calls. On a partial update the range is nulled and recomputed lazily on next access by scanning the already-filled magnitude cache array via SciChart.Data.Numerics.GenericMath.ArrayOperations.MinMax``1(``0[],``0@,``0@).
