style: 清理 Phase3 残留渐变与装饰性 emoji（企业级 UI 规范）

- 7 个文件 linear-gradient 改为 Ant 扁平实色（#1677FF/#52C41A/#FAAD14 等）
- 8 个文件移除装饰性 emoji（标题/卡片前缀），LangGraphAdmin 改为 el-icon，ReviewCenter 移除图标位
- TeacherOrders 重命名 gradient-* 类名、TeacherTeam 重命名 gradients 变量（均已为实色）
- 功能性箭头与用户可配置 icon 数据字段（ArticleCategory/gates/ProblemDomainManage）保留
