refactor(c-2): C-2c 旧蓝分流收官·令牌族删除 + 终审补漏

- uni.scss：删除 $brand-legacy-blue 族 4 令牌定义（C-2b 后页面引用已清零，无编译产物残留；uni.scss 独立编译 + dimension-detail 抽页编译均 OK，#4A9BD7 归零）
- butler/select.vue 补漏 3 处：终审全库扫描发现此前批次遗漏的小写 #4a9bd7（btn-change/btn-select 实底 + butler-card.active 描边）-> $brand-primary + 补 lang="scss"
- 终审结论：旧蓝族源文件剩余命中均为已登记保留项——wuxing-sandbox（深面板 chrome + canvas 五边形网格）、energy/detail、gate-guide-bar（深面板 chrome）；uni.scss 历史注释与审计脚本标签非翻转对象；dist/ 为陈旧构建产物
- 验证：butler C-2 PASS + node --check PASS；scripts/tmp_c2_verify.js 被外部进程误删后按原逻辑重建
