C3D-0281 · 260714 Huckaby: read the site extents via the active document done

READ-ONLY. Entity counts have been inconsistent across tickets (216/64/37), so this logs the active document name, the script Db filename and whether they are the same object, then measures CogoPoint extents through CivilApplication.ActiveDocument and model space through the active documents database.
