feat(group-members): 群列表对账云客总数+群详情成员墙(头像+昵称)

用户报两点:①微信群列表与云客群统计总数不一致(实测云客 1,864 vs 本地
2,012——friend_list/es 时代残留的 148 行 owner 组合已不在 getChatroomList
返回里);②群详情成员列表全是 wxid 无法识别。

- chatroom-stats 全窗模式加对账:名单取满(>=声明 total)才删本地不在
  云客名单里的 chat_group(wechat)行——页脚从此与云客一字不差;短页宁
  可不对账防误删
- backfill_group_members 增强:头像列(消息最新一条 sender_head_url)+
  customer 兜底 UPDATE(member_id=friend_id 命中本司好友补昵称/头像,
  覆盖未发言成员);full_sync 8b 原位生效
- 群详情 drawer 成员墙:头像+昵称网格(群昵称>好友昵称>wxid 回退+wxid
  副行),替代原 memberIds 原始串;仅微信 tab(WA 群成员未派生)

722 后端测试绿,前端构建过。
