fix: use pre-bundled wwobjloader2 worker for production builds (#7879)

Browse Source 
## Summary

The unbundled worker from 'wwobjloader2/worker' has ES module imports
that fail in production builds because Vite's ?url suffix doesn't bundle
dependencies.
Switch to 'wwobjloader2/bundle/worker/module' which is self-contained
with all dependencies included.

Fixes OBJ loading failing in production with Worker error events.
