- add a content textarea (size huge) after description, with en and pl phrases
- add content to Category.Fillable
- export classes.CheckHTML and run it from FormBeforeCreate and FormBeforeUpdate:
unsafe category content answers 422 on content, blank content is stored as NULL
YAML-driven Posts screen stores translatable markdown and regenerates
content_html in the plugin. Publish writes without access_publish are
refused; list and form queries stay on the principal without
access_other_posts.
