完善通讯录群详情展示：补齐群公告/群主/群管理信息

变更项：
1. 数据层新增群资料聚合查询，直接复用 is_owner/is_admin 字段返回群主与管理员列表。
2. 同步群信息时兼容提取群公告并落库，历史库启动时自动补齐 chat_room_announcement 字段。
3. 新增 /contacts/api/group_profile/<roomid> 接口，统一返回群公告、群主、管理员、成员数。
4. 通讯录群详情弹窗新增群主/群成员数/群管理/群公告展示，并在打开详情时自动加载。
5. 补充群成员精简查询头像字段，更新初始化 SQL 中 t_chatrooms 公告字段定义。
