feat: Add support for the ORA Grading MFE

[arbrandes]

The MFE is accessible by instructors in ORA exercises that have explicit staff grading steps.

The corresponding waffle flag is installed and enabled by default.

Depends on:

• [x] https://github.com/openedx/frontend-app-ora-grading/pull/185.

[arbrandes]

For the record, we need this fix to land before we can merge this.

[arbrandes]

This has also been rebased, but at a reduced priority since we haven't gotten the blocking upstream PR merged, yet.

[arbrandes]

This is now:

• targetting the Palm branch
• blocked on https://github.com/openedx/frontend-app-ora-grading/pull/183, as ORA grading doesn't currently support runtime config

Hi @arbrandes, I've tried ORA grading MFE, there was one issue I found, could you check it in this release. In Local deployment, when viewing individual submissions, I noticed that file download URLs were relative paths, because of that it could not be displayed, the url was https://{MFE_HOST}/openassessment/fileupload/submissions_attachments/... instead of https://{LMS_HOST}/openassessment/fileupload/submissions_attachments/... I think the problem could be from this file

  const rendererProps = {
    fileName: file.name,
    url: file.downloadUrl,
    onError: stopLoading,
    onSuccess: () => stopLoading(),
  };

I'm not sure this is an optimal way to fix the problem, but it could be

  const rendererProps = {
    fileName: file.name,
    url: file.downloadUrl && file.downloadUrl.startsWith("/") ? `${baseUrl}${file.downloadUrl}` :  file.downloadUrl,
    onError: stopLoading,
    onSuccess: () => stopLoading(),
  };

This may not affect files uploaded to S3, only files uploaded to local storage I think.

@vunguyen-dmt, do you mind opening an issue in https://github.com/openedx/frontend-app-ora-grading describing the problem you observed, including instructions to reproduce? It's not readily apparent - at least to me - that this is a problem with tutor-mfe.

In any case, I don't think that is a blocker to releasing in Palm, so I'm going to go ahead and merge this.
