Feature: Show count of QSOs to be uploaded to eQSL

[ofadam]

As an extra way to confirm that I'm about to upload a long list of expected QSOs to eQSL, I once had the ability to see how many total would be uploaded at /eqsl/Export. At some point, that information was removed from the page – it existed a while back.

That "total QSOs" number is present at /qrz/export, so would be nice to match.

Specifically, I have issues with GridTracker reliably sending QSOs to Cloudlog – so this gives me a quick way to check how many new QSOs I should have at a glance. Might that be something that could be added back?
