Add button to web UI of Transporter import results

When having used Transporter import and the results are displayed, the only way to continue is the edit the url in addressbar of the browser.

It's more user friendly when a button is added in the result page which redirects to i.e. Dashboard.

Version Beta v5.0
Pi-hole version is v4.3.2-391-ge0b3405 (Latest: v4.3.2)
AdminLTE version is v4.3.2-360-g88da85f (Latest: v4.3.2)
FTL version is vDev-a90f14b (Latest: v4.3.1)

On my browser, the teleporter import opens in a new tab, and the original dashboard tab remains open. When the import is complete, I close the new tab.

Perhaps that is a browser setting on my specific browser.

Should be addressed by
