Use player names in two-player briscola

Classic briscola has no partnerships: its "teams" are just the two
players, but the UI labelled them Team A/Team B.

- add is_individual_game() and GameView::player_name_for_team() to the
  model;
- the briscola table HUD reads "Alice 0 — 0 Bob (target 61)" and the
  seat panels drop the Team badge for two-player games;
- the deal summary and game-over screen name the sides and the winner;
- the waiting room and join preview hide the Team badge.

briscola a quattro and scopone keep their team labels, and the match
history table is unchanged.
