Keep `swagger` and `external-render-helper` as a standalone entries for external render. - Move `devtest.ts` to `modules/` as init functions - Make external renders correctly load its helper JS and Gitea's current theme - Make external render iframe inherit Gitea's iframe's background color to avoid flicker - Add e2e tests for external render and OpenAPI iframe --------- Co-authored-by: Claude (Opus 4.6) <noreply@anthropic.com> Co-authored-by: wxiaoguang <wxiaoguang@gmail.com>
