C3D-0202 · READ-ONLY: images, OLE frames and underlays done

Reports every OLE frame, raster image and PDF/DWF underlay with its layer, placement and source path, plus whether each source file still exists on this machine, to distinguish linked (fragile) images from ones that travel with the drawing. No changes.

C# payload

// READ-ONLY. What images are in this drawing and are they LINKED (fragile) or embedded?
// The snapshot showed 3 Ole2Frame on layer 0; OLE frames are links that break when the source
// moves or the file is sent elsewhere. Rasters attached by path are also links unless the path
// travels with the drawing. Report every image-bearing object with its source and placement.
// Nothing is modified.
var bt = (BlockTable)Tx.GetObject(Db.BlockTableId, OpenMode.ForRead);
Log("drawing: " + Db.Filename);
