Trump card: draw from the stack, no trump for wizards and jesters

- Deal the hands from the shuffled stack and draw the trump card from it,
  so the trump card is in nobody's hand and cannot be played
- A wizard or jester as trump card means no trump suit (previously a
  wizard let the dealer choose); remove the trump selection phase, the
  ChooseTrump action, the trump picker UI and the AI trump actions
- Completed tricks carry their round's trump card, so the table keeps
  showing the matching trump card while the last trick of a round is
  displayed
- Card corners are no longer rotated, so 6 and 9 cannot be confused
- Trump label explains why there is no trump (wizard, jester, last round)
- Tests: trump card never dealt, special cards give no trump, tricks keep
  their trump card
