Looks good - just one comment when a training data file was originally uploaded from an Excel file

src/SIL.XForge.Scripture/ClientApp/src/app/serval-administration/serval-project.component.ts line 338 at r1 (raw file):

    if (trainingData == null) return this.noticeService.show('File not found');

    this.fileService.onlineDownloadFile(FileType.TrainingData, trainingData.fileUrl, trainingData.title);

title is the original filename that was uploaded and wont end in .csv. All data is stored as CSV on our server (we do not store the original XLS or XLSX files if the user uploads an Excel file). Can you please have this set the file extension to ".csv" if the mimeType is text/csv?

Code quote:

this.fileService.onlineDownloadFile(FileType.TrainingData, trainingData.fileUrl, trainingData.title);

Thanks for the suggestion. I put the logic into fileService.ts since it might be useful for the auto-detection of the mime type. Let me know if that makes sense?

          // use the .csv extension explicitly if the MIME type is csv
          filename = filename.split('.')[0] + '.csv';
        }

This will return incorrect filenames for filenames like "test.data.xlsx". Something like this might be better?

if (blob.type === 'text/csv') {
  const extensionIndex: number = filename.lastIndexOf('.');
  filename = (extensionIndex !== -1 ? filename.substring(0, extensionIndex) : filename) + '.csv';
}

        if (blob.type === 'text/csv') {
          // use the .csv extension explicitly if the MIME type is csv
          filename = filename.split('.')[0] + '.csv';

You are right. How does this look?
