C3D-0359 · 168.1' and 122.0': make the dimension text read along the line, not horizontal [C3D-DIMALIGN] done

Sets Dimtih=false and Dimtoh=false as a per-object override on the two AlignedDimensions (handles 21C7B and 21C55) so the measurement rotates to align with the dimension line and reads up the arrows instead of sitting flat between them. The Standard dim style is not modified, so no other dimension changes. Recomputes and reads back the text rotation to verify.

// Make 168.1' and 122.0' read ALONG the dimension line instead of horizontal between the arrows.
// Per-object override only: Dimtih=false (text-inside not horizontal), Dimtoh=false. The dim
// style stays as-is, so no other dimension in the drawing changes.
var handles = new string[] { "21C7B", "21C55" };
Log("drawing: " + Db.Filename);
