fix(settings): valid HTML in setting tiles; start uploads in an effect (#291)

SettingTile rendered its description in a <p>, and many tiles pass
blocks (badges, Box, Text), so Settings had <div>/<p> inside <p> and
React warned on every page. Render it as a <div>. UploadCardRenderer
called startUpload() during render, which now updates the desktop
taskbar-progress hook mid-render; start it from an effect instead.
