补齐网页Cookie缺失字段并接入会话自动预取guid

- 新增 core/huya/web_cookie_fields.py:4 核心设备字段(guid 取自 wsLaunch 会话、
  _qimei_uuid42/__yamid_new/game_did 随机对齐格式)+ qimei 皮肤 + 22 个统计/会话字段
- elite_session 活动通道初始化时若缺网页字段,先 wsLaunch 预取服务端认可 guid,
  补齐 cookie 后重建会话;业务 RPC 统一走补齐后的 cookie
- 实测:账号 id=58(原始 16 字段登录态)checkUserBindGameAccount status=200
  (和平精英已绑定/收麦季)、getUserScore status=200(积分 4880)
- 附补齐方案与浏览器实测来源记录 docs/HUYA_CHAT_缺失字段补齐方案.md

"""虎牙网页 Cookie 缺失字段补齐生成器。
账号 App 登录态只有 16 个 udb_* 认证字段,而活动/商城 WSS 需要完整的网页设备态。
浏览器实测(evidence/browser_cookie_harvest/report.md)确认:
- ``udb_deviceid/udb_guiddata/udb_anobiztoken/udb_anouid`` 由匿名设备态协议
core/huya/anon_device.pymiddle + anonymousLogin)签发;
- ``guid/_qimei_uuid42/__yamid_new/game_did`` 由页面 SDK 脚本写 document.cookie
无服务端签发接口。其中 ``guid`` 与会话强绑定:**wsLaunch 响应返回的新 guid 必须
回写进 cookie**,否则 getConfig 无响应(2026-09-01 实测);
``_qimei_uuid42/__yamid_new/game_did`` 为设备标识,随机值格式对齐即可;
- 其余统计/会话字段(SoundValue/Hm_*/rep_cnt 等)服务端仅记录,可随机生成。
2026-09-01 全链路实测:账号 id=58 补齐后 checkUserBindGameAccount 返回
status=200(和平精英已绑定)、getUserScore 返回 status=200(积分 4880)。
