fix(workspace): hidden bullet actions on phones, no second extract, notice layout

- The floating bullet actions only react to hover on devices with a real
  pointer; a tap on a phone made the invisible buttons clickable.
- A bullet that is only a note link (plus hashtags) can no longer be
  extracted: button and /extract are hidden, the server answers 400.
- Extract notice on phones sits above the bottom navigation, text on
  top (two lines max) with the actions below.
- Release v0.26.1.
