Add Z-position logging and disable culling for debugging

Browse source 
Enhanced STORMWIND.WMO logging to show:
- centerZ: local Z position of group center
- sizeZ: height of the group
- worldZ: world Z position after transform

Removed all culling logic to see ALL groups rendering.

This will help identify which groups are positioned HIGH (floating shell).
User reports the shell is 'larger and floating above' the real cathedral,
so we need to find groups with unusually high Z positions.
