<!--
  共享通知列表组件
  ------------------------------------------------------------
  自包含: 数据拉取 / SSE 实时刷新 / 详情弹窗 / 全部已读 全部封装在内.
  任何角色页面 (workbench / home / 独立 messages 页) 只需:
    <NoticeList :limit="5" />                       // 嵌入式小列表 (默认有"全部已读"顶部按钮)
    <NoticeList :limit="50" :show-category="true" /> // 完整页列表 (显示分类标签)
    <NoticeList :limit="5" :show-header="false" />  // 嵌入式,父 section-title 自己带按钮

  Props:
    limit         Number  拉取条数,默认 5
    showCategory  Boolean 是否显示 [通知/待办/系统] 分类标签,默认 false
    showHeader    Boolean 是否显示组件自己的"全部已读"顶部按钮,默认 true
    emptyText     String  空列表文案,默认 '暂无通知'

  复用: 调用方不再写 notice-item / dot / SSE 订阅 / 详情 dialog,3 处变 1 处.
