Missing Authorization in Layout Library REST API (Unauthenticated Access)

An unauthenticated attacker could call the layout-list REST endpoint to retrieve layout library data, including potentially sensitive template content, without any authentication or capability check. The fix adds a current_user_can(‘edit_posts’) check that returns HTTP 403 for unauthenticated or unauthorized requests.
