Polyline3D tessellation now separates spline-fit curve vertices (flag 8)
from frame control points (flag 16): the curve vertices form the rendered
wire while control points are exposed as key_vertices for snap. Polylines
without spline flags are unchanged.
DXF post-load fixup now also converts AttributeEntity and AttributeDefinition
rotation from degrees to radians (group code 50 bug), matching the existing
LinearDimension fix. Attribute text rendered from DXF files now has correct
orientation.

- polyline.rs: TruckConvertible/Grippable/PropertyEditable/Transformable
for all three polyline types; Polyline2D handles bulge arcs via the
same truck Wire path as LwPolyline; Polyline and Polyline3D use
TruckObject::Lines for straight-segment rendering
- ray.rs: Ray renders as base→+1e6; XLine renders as ±1e6; both have
base-point and direction grips; mirror correctly reflects direction
vector; base X/Y/Z and Dir X/Y/Z exposed in properties panel
- traits.rs: dispatch all five new entity types through
to_truck_entity, grips, geometry_properties, apply_geom_prop,
apply_grip, apply_transform
