Add Kaiser, Crazy 8s and Wizard

Three more card games, engine to screen.

Kaiser: 32-card prairie trick-taking with bidding, the five of hearts
worth five and the three of spades costing three. Bidding is capped at
ten because ten is all a hand can be worth, and a losing score gives the
game a floor — without one a table that keeps bidding and going down
never reaches a result.

Crazy 8s: eights are wild and name the suit in force, which is why the
table states that suit in words rather than leaving it to be read off
the pile. Blocked rounds are scored rather than hanging.

Wizard: the 60-card deck, one more card dealt each round until the pack
runs out, bid your tricks exactly. The shared card model gains WIZARD
and JESTER ranks, so every ordinary deck now builds from Rank.standard
rather than walking the whole enum.

Also fixes a lobby bug this would have hit: hosting seated the
catalogue minimum rather than the table the host had just set up, so a
six-handed game would have been rejected by its own rules engine.

164 engine tests pass locally.
