feat(ui): unify link/address styles and set primary header color

- Links use primary color; removed leading icon
- Show API address when website is missing; use secondary text color, non-monospace
- Parse base_url from Codex TOML; change fallback copy to "未配置官网地址"
- Use primary color for the top-left header title
- Clean up unused imports
