🐛 Fixed error when rendering static page from dynamic route

no issue

- When having following routes.yaml configuation and theme runing API v3:
routes:
  /:
    data: page.home
    template: home

- There was an internall error in meta layer: `Cannot read property 'website' of undefined` which was caused by not being able to read primary_author on a fetched page
- We need to include authors and tags for pages, the same way we do for posts to prevent this error (as they should have identical properties from meta layer perspective)
