C3D-0207 · Vicinity map at 33.51902614, -84.16534004 done

Re-fetches the vicinity map centred on the coordinate the user supplied and repoints the VICINITY image definition at it. Saved under a new filename because the previous PNG is locked open by the running Civil 3D session. The frame keeps its position and size; the image lives in the job folder, not Windows temp.

C# payload

// Point the vicinity map at the coordinate the user gave: 33.51902614569263, -84.16534004126642.
//
// Written to a NEW filename because the previous PNG is locked open by this Civil 3D session -
// overwriting it in place fails with a permission error while the drawing holds it.
//
// Only the SourceFileName of the VICINITY definition changes; the frame on the sheet keeps its
// position and size. The image lives in the job folder, never the Windows temp folder - a temp
// path is what left this frame blank in the first place.
