- Scale popup dropdown replaces cycle behavior; paper-space viewport scale
editable when a viewport is active/selected
- CANNOSCALE persisted via DXF $USERR1 (read on open, write on save)
- PSLTSCALE: linetype dash lengths scaled by viewport anno_scale so dashes
appear uniform physical size in paper space
- MultiLeader: arrow size, dogleg length, and text height scale with
anno_scale; leader line paths (world coords) stay fixed
- Leader: arrow size and hookline length scale with anno_scale; also
corrects world_offset subtraction that was previously deferred to the
TruckObject::Lines path
