Fix scoped package import for custom view

- Changed component reference from 'payload-feature-flags/views' to '@xtr-dev/payload-feature-flags/views'
- This fixes the "Module not found: Can't resolve 'payload-feature-flags/views'" error
- Bumped version to 0.0.4

The importMap.js was trying to import without the @xtr-dev scope prefix.
