feat(static): improve static files handling and permissions in Docker

- Add script to set correct permissions on static files after collectstatic
- Introduce collectstatic command in entrypoint with permission fixing
- Add WhiteNoise middleware for efficient static file serving without DB access
- Configure WhiteNoise static files storage backend in settings
- Set STATIC_ROOT path properly for Docker container environment
- Add fallback static files serving in Django urls for production without nginx
- Enhance inventory_detail.html scripts to log errors if JS files or components fail to load
- Add whitenoise package to requirements for static file serving support
