Bulk results modal: tweak DataTable styling

[norrisng-bc]

Description

This fixes the styling for the bulk results modal/table.

Previously:

• Long email/results strings would wrap
• Spacing was inadequate along the right side of the results column
• The table/modal would be to narrow if the results string for all emails is short

Also, the DataTable's export-filename declaration was too lengthy, so it has been moved to a separate line.
