Create a B-spline surface (or triangulated shell) from a 2D grid of height values.
The grid is interpreted as Z heights at evenly spaced (X, Y) positions. Row index maps to Y, column index maps to X.
2D array of Z values, at least 2x2
Physical dimensions and Z scaling
Result containing the surface shape (may be a Face or Shell depending on grid complexity)
