fix(dxf): stop writing a duplicate *Active viewport (#319)

Browse source 
Opening a DXF whose active viewport is stored uppercase (*ACTIVE),
editing and re-saving produced a file with two full-window model-space
viewports — the file's own *ACTIVE plus a fresh *Active we add on save.
The reserved viewport name is case-insensitive, so the two didn't
collapse and other CAD apps drew them one on top of the other, which
read as the copied objects being linked / "reacting as one".

save_model_tiles_to_vports dropped existing active viewports with a
case-sensitive `name != "*Active"` filter, so an uppercase *ACTIVE
survived and sat next to the new entry. Route every *Active comparison
(save filter + camera/tile restore) through a case-insensitive
is_active_vport_name helper so the file's record is recognised and
replaced instead of duplicated.

Also bumps acadrust to #99f75fe (merged PR #1): the ASCII DXF writer now
emits shortest round-trippable floats instead of the full 16-digit
expansion, halving the round-tripped file size.
