fix(beautify): 补齐 3 处 BrandColors 缺失 import + 新增品牌色引用完整性审计

- sleep-checkin / profile-main/profile：script 内使用 BrandColors.* 但从未 import
  （D31 收编时漏加 import，运行时 ReferenceError）
- emotion-checkin：改导入 BrandColors，去掉 3 个已不再使用的具名导入
- scripts/audit-brandcolor-integrity.js：一次性体检四类历史回归
  'BrandColors.xxx' 字符串 / 缺少 import / import 落在 </script> 后 /
  具名导入不存在；退出码可直接接入 CI
- 审计结果：四项全 0，3 文件 node --check 通过

+ *   2) BrandColors.xxx 使用但未 import —— 运行时 ReferenceError / undefined
+ *   3) import 落在 </script> 之后 —— 模块作用域外，运行时标识符未定义
