feat(editor): export NPC/M2 model textures as PNG with the zone

Browse source 
TextureExporter::collectUsedTextures only picked up terrain textures, so
exported zones were missing every texture referenced by NPC creature models
and placed M2 doodads. Added collectM2Textures() and unified the export
collection to include terrain + all referenced M2 paths, so the rendered
zone is fully self-contained in the PNG/WOM open formats.
