fix(framework): player_login.version 改为数字 versionCode(联调登录成功)

真机联调发现：协议 version 字段=数字 versionCode（源码 8 处 data.version=GameData.versionCode），
框架原发字符串 '1.1' 被服务器版本校验拒绝(kick_server 检查到新版本)。改为数字后登录成功
(state:0 playerid:430511)。
- ChannelIdentity/LoginRequestData.version: string→number，去掉冗余 versionCode 与未发送的 '1.1' 串
- query-string version 解析为数字；测试 fixture 同步
