ci(engineering): Gitea Actions 门禁 + 前端测试设施 + 版本注入修复

- .gitea/workflows/ci.yml:后端 gofmt/vet/test + 前端 lint/test/build 双 job 门禁
- vitest + @testing-library + jsdom 落地,14 个命脉用例:useListQuery 乱序丢弃/卸载中止、
  http.ts 401 单飞刷新+队列重放+失败登出+silent 直拒、审计防抖、StepDeploy 部署目标、query-utils
- 版本注入断裂修复:main 补 buildTime/gitCommit 符号,build.sh/Dockerfile 注入 main.version,
  /health 返回真实版本,前端 package.json 版本对齐 2.0.0
- gofmt 清零(8 个存量未格式化文件)
