style(page-title): 补漏——战略地图看板页标题弱化 + KPIListView 标题 emoji 清零

- StrategyMap.vue: 页内 h2 19px/600/深色（与路由标题「战略地图看板」基本同名）降为
  div.page-subtitle 14px/500/#64748B（保留地图名+版本+状态等增量信息，不再充当 H1）
- KPIListView.vue: 组件 h3 图标默认值 '📊' 置空（v-if 渲染），分类标题与明细卡头
  '📋' 改为 Lucide 内联 SVG（clipboard-list，18/16px，#64748B）
- 仅模板与样式：不动 MainLayout、不改接口/数据/路由 key、不碰 MapCanvas.vue
