feat(meeting): 会议详情页参会人 CRUD + BizProjectPlan audit 字段

- 后端: BizMeetingAttendee 增 list/add/update/delete 4 端点
  按手机号定位 sys_user (无则新建, 用户名=密码=phone, role_type='doctor')
  Mapper: insertWithProfile (一次写完整档案) + deleteByPrimaryKey
  Service: insertByPhoneWithProfile (重复参会人抛友好异常)
- #4 配套: BizProjectPlan.auditOpinion/auditBy/auditTime + 关联项目名
  BizProjectPlan.projectName (LEFT JOIN biz_project) 用于 #4 通知 content
- 前端 MeetingDetail.vue: 劳务材料 tab 内, 劳务明细表 file-row 下方
  直接出表 (无表题), 含姓名/手机/单位/科室/职称/劳务费/签字状态/操作
  新增/编辑 dialog 共用, 删除走 ElMessageBox.confirm 二次确认
- 触发 #5: 新参会人 POST 时也发会议邀请通知 (与 BizMeetingController.add 一致)
