C3D-0404 · Create HCWA property-line family layers (skip existing) [C3D-PROPLAYERS] done

Creates the 8 HCWA property-line layers from the As-built CAD Standards PDF - LAND_LOT_LINE, LAND_LOT_LINE_TEXT, LOT_NUMBER_TEXT, PROJECT_BOUNDARY, PROJECT_BOUNDARY_TEXT, PROPERTY_LINE, ROAD_RIGHT-OF-WAY, ROAD_RIGHT-OF-WAY_TEXT - skipping any already present. Verifies all 8 exist.

C# payload

// Create the HCWA property-line family layers (exact names from the standard). Skip any already
// present. Colours matched to what the drawing uses per discipline where a sibling exists,
// else a sensible default; the standard specifies names + type, not colour.
Log("drawing: " + Db.Filename);
var lt = (LayerTable)Tx.GetObject(Db.LayerTableId, OpenMode.ForWrite);

// name -> ACI colour
var want = new (string name, short color)[] {
    ("LAND_LOT_LINE",           7),
    ("LAND_LOT_LINE_TEXT",      7),
    ("LOT_NUMBER_TEXT",         7),
    ("PROJECT_BOUNDARY",        3),
    ("PROJECT_BOUNDARY_TEXT",   7),
    ("PROPERTY_LINE",           7),
    ("ROAD_RIGHT-OF-WAY",       6),
    ("ROAD_RIGHT-OF-WAY_TEXT",  7),
};

int created=0, existed=0;
