feat(editor): auto-convert placed M2 objects to WOM on zone export

Browse source 
- Zone export now converts all placed M2 models to WOM open format
- Deduplicates: each unique M2 path converted only once
- WOM files saved to output/MapName/models/ with original path structure
- Uses WoweeModelLoader::fromM2() for M2→WOM conversion
- Combined with PNG texture export, zones can now be fully distributed
  without any Blizzard proprietary files

Full open format export pipeline:
  Terrain: ADT→WOT/WHM | Textures: BLP→PNG | Data: DBC→JSON
  Models: M2→WOM | Buildings: WMO→WOB (manual) | Map: WDT→zone.json
