wmo: enable portal culling by default after AABB transform fix

Browse source 
The AABB transform bug (direct min/max transform was wrong for rotated
WMOs) was fixed in a prior commit. Portal culling now uses the correct
world-space AABB computed from all 8 corners, so frustum intersection
is valid.

The AABB-based test is conservative (no portal plane-side check): a
visible portal can only be incorrectly INCLUDED, never EXCLUDED. This
means no geometry can disappear, and any overdraw is handled by the
z-buffer. Enable by default to get the performance benefit inside WMOs
and dungeons.
