Name each install, fix the notification badge, switch to Archivo

- Settings > General: an App name (super admin) for the installed app.
  The manifest's name/short_name, the iOS head tags and the loading
  page's title use it, so two installs on one phone can be told apart.
- Notifications get a real badge (white stone silhouette): Android masks
  the badge by alpha, so the opaque app icon showed as a square.
- The loading and offline pages load the app's font.
- The font is now Archivo (variable, one request for every weight),
  matching the marketing site.
