fix(ui): unify tie-for-lead result across lobby + game (shared victory, not a draw)

Bring the online lobby badge and the in-game 'you won/lost' text to the
same competition ranking the hotseat seat medals use: in a 3-4 player game
a TIE for the lead is a SHARED victory for the top scorers and a placed
finish for those below — not a full draw for everyone (winner() is -1 on
any tie, so isWinner alone conflated them). An aborted game and a genuine
all-level finish stay a draw; a win by resignation (winner at a not-higher
score) is unchanged.
- result.ts: resultBadge no-winner branch ranks by final score; placeBadge
  helper; resigned seats excluded from the ranking.
- Game.svelte: resultText aligned (shared lead = won, below = lost).
