- feat: Run the backstage upgrade.
- fix: Restore GitHub sign-in requirement after frontend architecture upgrade
…pgrade The upgrade to Backstage 1.49.x migrated the frontend from the legacy `@backstage/app-defaults` architecture to the new declarative frontend system using `@backstage/frontend-defaults`. As part of that migration, App.tsx was reduced from ~109 lines to 7, and the explicit GitHub sign-in page configuration was dropped along with the old boilerplate. In the old system, the sign-in page was overridden via the `components` option of `createApp` (see the pre-upgrade App.tsx): https://github.com/openedx/openedx-backstage/blob/e66d00a/packages/app/src/App.tsx#L38-L50 components: { SignInPage: props => <SignInPage {...props} auto providers={[githubProvider]} /> } In the new declarative frontend system this override is done via a `SignInPageBlueprint` extension from `@backstage/plugin-app-react`: https://backstage.io/docs/frontend-system/architecture/extensions Without this, the new system fell back to attempting guest sign-in, which fails because guest is explicitly disabled in app-config.yaml (`guest: null`). The error was: "You cannot sign in as a guest, you must either enable the legacy guest token or configure the auth backend to support guest sign in." The fix creates a `signInPage` extension in `modules/nav/SignIn.tsx` using `SignInPageBlueprint` with `githubAuthApiRef` (now exported from `@backstage/frontend-plugin-api` rather than `@backstage/core-plugin-api`) requiring openedx org membership, and registers it in `navModule` alongside `SidebarContent`.
