C3D-VICMAP · Place vicinity map image running

Attaches the Google Static Maps vicinity image (roadmap, zoom 14, marker on site) above the VICINITY MAP label on 22X17 C, 2.6in square with a border.

C# payload

// Attach the vicinity map raster above the "VICINITY MAP (NOT TO SCALE)" label on 22X17 C.
// Google Static Maps roadmap, zoom 14, centred on the site (33.6562379,-84.5937887) with a
// marker. Label sits at (8.48,0.51)-(9.83,0.60), so the image is centred on x=9.16 and its
// bottom edge placed just above the label. Square image -> square placement.
// Also draws a border around it. Host owns Tx; host regens after commit.
