lin-xin/vue-manage-system ? reverse-engineered prompt

Build me a clean admin dashboard template in Vue 3 that feels ready for a real project.

I want a login and register flow, a main dashboard home page, and a full admin layout with sidebar navigation, top bar, and responsive content area. It should include common pages like tables and forms, some simple chart views, a rich text and markdown editor, image upload with drag and crop support, role based permission handling, nested menus with up to three levels, custom icons, and a light and dark theme switch. Use the standard UI components from Element Plus, keep the code in TypeScript, and manage state in a simple modern way. Make it polished, easy to extend, and suitable for a backend management system. If you need to check current docs for any library details, go ahead and look them up online.
