feat: 删除 admin 会议全览菜单 + 死页面 admin/Meetings.vue

admin 账号不关注会议, 移除 admin 视角的会议入口。

清理:
- router L29: 删除 admin-meetings 路由
- AdminLayout L78: 删除「会议全览」菜单项
- 删除 ry-vue3/src/views/admin/Meetings.vue (~95 行死页面, 同 admin/Projects.vue 一样是早期未完成桩)

Calendar icon 仍由 leader/manager/doctor/executor/sponsor 角色使用, 保留 import。
