C3D-LEGEND2 · Rebuild legend as a proper table done

4-row grid table: Outfall SSMH (blue circle), SSMH bolted (gray filled), Outfall sewer (green line), 40' easement (cyan line, SAME continuous linetype as sewer). Nothing else touched.

C# payload

// Rebuild the LEGEND as a clean table (grid + rows), replacing the deleted one.
// Row symbols match the real layer styles: Outfall SSMH (blue open circle), SSMH bolted (gray filled
// donut), Outfall sewer (green continuous line, matches SEWER_LINE), 40' Sanitary Sewer Easement
// (cyan continuous line, matches SEWER_EASEMENT — same linetype as the sewer line, just color-coded).
// Ambient Tx/ModelSpace globals only.
