chore: 移除项目内无用代码（28 文件）

- 清理任务面板/SPA 化改造遗留的未使用变量与函数（模板管理配套 6 函数、
  payloadForDisplay/showTip/hasRunning/schedulePoll/removeMatchedRowLocally 等 30+ 处）
- 清理未使用 import（getBrandTemplateXlsxUrl/uploadTempFileToJava/getProductRiskTasksBatch 等）
- useTaskProgressLoop 改为仅类型导入；progress/task-request 缓存未用参数精简
- DeleteBrandRunService 删除永不执行的 taskItems 死分支
- 全量 vue-tsc（含 --noUnusedLocals/--noUnusedParameters）0 错误；648 测试全过
