C3D-VICOLE · Embed vicinity map (OLE) error

Embeds the vicinity map into the DWG as a Static OLE frame from a LOCAL temp PNG, so the image travels with the drawing and there is no OneDrive/raster path to break or hang on. 2.6in square above the VICINITY MAP label, with border.

C# payload

// Vicinity map, EMBEDDED (OLE) so it travels with the DWG - no external file reference.
// Previous attempt attached it as a RasterImage pointing at a OneDrive path: the def.Load()
// blocked while OneDrive hydrated the file, the ticket blew past its timeout, and the drawing
// was left depending on a path that breaks the moment the file moves or is unsynced.
// Source is a LOCAL temp PNG (Google Static Maps, roadmap z14, marker on site); it can be
// deleted afterwards because the bytes live inside the drawing.
// Placed above the "VICINITY MAP (NOT TO SCALE)" label at (8.48,0.51)-(9.83,0.60).
// Host owns Tx; host regens after commit.
