refactor(c-2): C-2a-4b 旧蓝分流·大家伙批次 7 文件

- child-index：Flat Rounded clay 设计系统整体迁移品牌橙——设计系统注释/
  points-card 渐变/边框/双重阴影、streak-badge 描边阴影；数据类目槽
  task-cat--life/quick-icon--growth -> sky-600 rgba(2,132,199,x)（防与
  study/tasks 的 sky-500 及既有橙槽撞色）；补 lang="scss"
- parent-index：stat-icon-orange/act-add 名橙实蓝 -> 恢复品牌橙语义；
  milestone-trophy/pending-icon--blue/advice -> info 蓝；
  JS 渐变蓝槽 -> info 蓝渐变（第 4 槽已橙禁撞色）
- index-home：3 处 JS 渐变蓝槽 -> info 蓝渐变（同上禁撞色）
- wuxing-sandbox：深海军蓝面板仅翻品牌氛围层——ambient 光晕 + toggle
  选中态渐变/描边；#8FC5E8 面板 chrome 与 #42A5F5 水行语义保留
  （chrome 翻橙会与火行 #FF6B35 撞色）；补 lang="scss"
- articles.vue：弃 $c-brand-legacy 局部声明（含 C-2 移交注释块），
  filter-chip.active/article-category 内联 $brand-primary + rgba(249,115,22,0.1)
- dimension-detail：canvas 趋势图线/区/点 -> #F97316 + rgba(249,115,22,0.1)
- member-detail：home 槽 color/gradient -> 品牌橙（与 FamilyRelationGraph
  home 槽一致）

验证：6 个 style 文件 C-2 视觉变更验证 PASS（含块级规则 + sass 数值
规范化 0.30->0.3/0.10->0.1）；5 个 JS 触及点计数断言全中；7 文件
node --check 通过；旧蓝族残留扫描 0（wuxing chrome/水行为故意保留）
