feat(editor): NPC models load from WOM open format before M2 fallback

Browse source 
NPC creature renderer now checks for WOM open format models in
custom_zones/models/ and output/models/ before falling back to M2
game data files. This completes the WOM integration — both placed
objects (via terrain_manager) and NPC creatures (via editor viewport)
can render from the novel open format.

WOM→M2Model conversion includes bone weights, textures, render batch,
and material setup — same pipeline as the client-side WOM loader.

Loading priority: WOM (open format) → M2 + skin (game data)
