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.
Converts the website from a single-page design with anchor links to a full multi-page application. This change improves site organization, navigation, and scalability.
- Adds new top-level pages: `/news`, `/events`, and `/about`.
- Introduces a new section for the 40th Anniversary at `/40th-anniversary`, including a proposal sub-page.
- Updates the default layout with a new navigation menu, a promotional banner, social links, and page transitions.
