fix(game): refactor ServerPlayerState and update ServerGameState::updateStateByCard logic

- Replaced `handCard_` with `handCard` in `ServerPlayerState`.
- Updated `updateStateByCard` in `ServerGameState` to handle card validation and player actions.
- Made `updateStateByCard` virtual in `GameState`.
