C3D-0387 · READ-ONLY: what layer are the grease-trap symbols + label on [C3D-GT2] done

Finds the GREASE TRAPS label and reports its layer, then lists the circles and block inserts within 200 ft of it (the double-circle grease-trap symbols) with their layers.

C# payload

// The "PROP. 1500 GAL GREASE TRAPS" callout points at two side-by-side double-circle symbols.
// Find the label, then find the circles/blocks near where its leader points, and report layers.
Log("drawing: " + Db.Filename);
