feat(editor): convert NPC creature models to WOM during zone export

Browse source 
Previously only placed M2 objects were converted to the WOM open format.
NPC creature models stayed as references to game M2/skin files, which
meant exported zones still depended on proprietary Blizzard assets to
render their NPCs. Now the exporter walks both placed objects and NPC
spawns and emits a WOM for every unique M2 path, making zones fully
self-contained.
