fix(blackbox): the timeline's labels on a narrow timeline, marks out of view, the cab on a short window

Browse Source 
- The hover label and the clock bubble keep to the left edge on a
  narrow timeline instead of throwing in Render.
- A mark is told under the pointer only when it is drawn: within the
  plot and the time shown.
- The device groups are clipped at their own width, not 4 px short.
- On a short window the cab card scrolls, so the list above it keeps
  room for a few rows.
