feat(content): add draft support for content collections

This commit introduces a draft system for the 'events' and 'news' collections. A `draft` boolean field has been added to the content schema, and frontend queries are now updated to only fetch and
display content where `draft` is `false`. This allows content to be created and saved without being publicly visible, improving the publishing workflow.
