Keep last round's summary visible until all bids are placed

The round summary used to disappear after a fixed 5 seconds. It is now
derived from the game state: the previous round's result is shown while
the new round is in bidding and hides once card play starts. This also
survives a page reload.

- Drop the client-side round timer from useWizard
- On narrow screens show the summary in the page flow so it does not
  cover the bid buttons
