refactor(game): 重构游戏动作处理和WebSocket连接管理

- 重构sendGameAction函数参数结构，添加上下文支持
- 新增sendStartGame和sendLeaveRoom函数统一处理游戏开始和离开房间逻辑
- 移除路由相关依赖，简化ChengduGamePage组件
- 更新WebSocket客户端实现，添加状态变化订阅功能
- 移除requestId生成函数和相关参数，精简消息结构
- 优化座位玩家卡片数据模型，移除在线状态和金钱字段
- 整理游戏阶段常量定义，添加标签映射
- 移除过期的游戏状态字段如needDraw、lastDiscardTile等
- 添加座位类型定义和改进游戏类型文件组织结构
