fix(dbc): runtime detection for ItemDisplayInfo texture field indices

Browse source 
Revert static JSON layout changes (15-22 back to 14-21) since WotLK
loads the Classic 23-field DBC. Add getItemDisplayInfoTextureFields()
helper that detects field count at runtime and adjusts the texture
base index accordingly (14 for 23-field, 15 for 25-field).
