Before this commit, the status bar field could be displayed in 2 ways:
- in small screens: as a dropdown
- in larger screens: as an inline list of buttons
This commit centralizes both of these approaches into a dynamic display
that fits the available space:
- the current stage is always displayed;
- previous stages are displayed behind or contained in a dropdown if not
enough space;
- next stages are displayed behind or contained in a dropdown if not
enough space.
