fix(export+calls): 同类owner错位问题全面修复(群导出不按owner过滤+群语音客户点击走群聊路由)

- /api/export/chat-html: room 查询忽略 owner(chat_group owner 错位同
  ChatTimeline,群列表/聊天页的导出按钮原来会导出空文件)
- CallList viewCallCustomer: talker 以 @chatroom 结尾→group-chat 路由
  (原走 1:1 路由按 talker_id 查@chatroom 恒空)
- TDD: 群消息在 ownerB 名下用 ownerA+room 导出仍能拿到;428 测试绿
- 实测:错位 owner 导出 43304 群返回 15002 个消息元素
