Add briscola chiamata

Five-player briscola with a descending calling auction and a secret
partner. Starting with the player after the dealer, each player bids a
lower rank (A > 3 > K > H > J > 7 > 6 > 5 > 4 > 2) or passes; once the
standing bid is the two the auction continues on points (62, 64, ...).
The last player standing must bid, and the winner names any card of the
won rank: its holder is the secret partner, or the caller plays alone
when it is one of their own cards, and its suit becomes the trump. The
calling side must reach 61 (or the raised target); a 60-60 deal with the
plain target is a patta and is replayed. A match is a single deal, so
the caller and partner (or the lone caller) against the other players
map onto the platform's two-team result, Elo and match history.

The rules live in tavolo.briscola.chiamata with the
BriscolaChiamataEngine adapter registered alongside the other briscola
variants; the partner's role and the side totals stay hidden until the
called card is played. The web client gets a five-seat table, the
auction panel with legal bids and point raises, the call picker, the
reveal bands and a chiamata-aware final summary.
