修复会议详情页显示裸user_id的问题（第9章复测发现）

创建/详情/更新/取消/我的回应这5个会议接口的 organizer.display_name/participants[].display_name
实测恒等于裸 user_id，只有列表接口 GET /meetings 会真的解析姓名。之前的注释误以为"响应已带
姓名解析"对所有会议接口都成立（可能是当时只测过列表接口就下了结论），这次复测用真实创建的
会议逐个接口验证，证伪了这个假设。

MeetingDetail 接入已有的 useUserNames（日报/月报详情页已经在用同一套机制），发起人和参会人
姓名解析不出来时不再显示裸 uid。同时更正了 MeetingCard 上那条误导性注释，说清楚它只对列表
接口成立。
