* DWG read: keep a polyline's vertex order when handles are not ascending (fixes #1856)

acadrust 0.6.4 assembled a polyline's VERTEX records in handle order and discarded the polyline's owned vertex-handle list, so a vertex inserted into an existing polyline (and therefore given a higher handle) moved to the end of the outline. 0.6.5 reads the owned list and orders each polyline's vertices by it.

Adds a regression test that writes a DWG whose second 3D-polyline vertex has the highest handle, reads it through the DWG bridge, and checks the order for AC1018 and AC1032.
