feat(games): unify ApplyMove signatures + remove unused player conversion

Updated TicTacToeRules and BattleshipRules to implement ApplyMove(state, playerIdx, payload) (bool, bool, int) as required by GameRules.

Added win/draw resolution logic directly inside each game’s ApplyMove return.

Removed obsolete convertToGamePlayers helper.

Updated GenericMatch to call AssignPlayerSymbols with []*structs.Player directly.

Ensured all rule implementations now fully satisfy the GameRules interface.
