feat: MeetingDetail 参会人表改用 GrTable + 移除合计行

GrTable 增强 (sibling subagent 已完成重构):
- mobile 模式从 el-table expand 行改为 el-descriptions 卡片列表
- 每行一张卡, 显示所有列
- 通过 extractDefaultSlot 抓取自定义 #default slot 的 vnode
- renderTemplate 在 mobile 卡片里渲染原始 vnode (含 maskPhone/maskBankCard/
  maskIdCard/openPreview/el-link/el-tag 等自定义 template)
- 支持无 prop 自定义 template 列在 mobile 正确渲染

MeetingDetail 改动:
- el-table → GrTable (show-summary 移除, 不要合计行)
- 移除 attendeeSummary 函数 (合计不再需要)
- 移除之前 mobile attendee-table 紧凑规则 (mobile 走卡片分支, 不需要)
- v-bind $attrs 透传 v-loading/border/size 给桌面 el-table
- 修复 GrTable 闭合标签 (</el-table> → </GrTable>)

桌面端 el-table 完整渲染不变 (sibling 完整保留透传逻辑)
mobile 端: 每行一张 el-descriptions 卡, 27+ 列全部展示, 自定义 template 正常渲染
