refactor: simplify configuration by removing factory pattern and overengineering

- Remove SiteConfigBuilder component and all factory files
- Simplify preset-ifla to only provide essential plugins (sass, ideal-image, search)
- Replace factory exports with direct configuration pattern in all site configs
- Remove deep cloning workarounds that were masking the real issue
- Fix LRM navbar docId reference from 'intro' to 'intro/intro'
- Ensure each site builds its own config object without shared state contamination
