Apply dark theme to all UI pages

- Convert registry list, docker detail, package detail, maven detail pages to dark theme
- Use layout_dark instead of layout for all pages
- Update colors: bg-[#1e293b] cards, slate-700 borders, slate-200/400 text
- Mark unused light theme functions with #[allow(dead_code)]
