Add cathedral WMO detection logging for duplicate model debugging

Added detailed logging in ADT loader to identify cathedral WMO duplicates:
- Log all WMO filenames from MWMO chunks with index numbers
- Flag and highlight any WMO containing "cathedral" or "Cathedral"
- Log cathedral placement positions from MODF chunks

This will help identify if both WotLK and classic cathedral models are
being loaded from the same ADT tile, causing the floating duplicate effect:
- World\wmo\Azeroth\Buildings\Stormwind\SW_CathedralDistrict.wmo
- world/wmo/azeroth/stormwind/zClassic/cathedral.wmo

The logs will show which cathedral variants exist and their exact positions
to determine if one should be filtered/hidden.
