LP#1482400: increase visibility of record count during order activation

The progress dialog shown during the asset-creation phase of order
activation now also displays record counts above the progress bar.

To test:

[1] Following the test plan of the previous patch, verify that the
    progress dialog now displays and updates text above the progress
    bar indicating how many records it has processed, e.g.,
    "Bib Records Merged/Import: 25"
