fix(game): patch Desync DoS vulnerability with strict majority consensus (#3956)

Resolves #3959

## Description:

This PR fixes a Denial of Service (DoS) vulnerability in 1v1 matches
related to desync reporting. The `findOutOfSyncClients` logic previously
forced a game-ending desync if half or more players reported conflicting
hashes (`outOfSyncClients.length >= Math.floor(this.activeClients.length
/ 2)`). In a 1v1, this meant a single malicious player sending a bad
hash could trigger a global desync, crashing their opponent's game
session.

The logic has been corrected to require a **strict majority** (`>
Math.floor(this.activeClients.length / 2)`) to declare a lobby-wide
desync. In a 1v1 game, a single malicious actor will now simply be
flagged as the out-of-sync client and disconnected, allowing the honest
player to continue their session uninterrupted.
