[1.x] Update two-factor-authentication-form.blade.php (#414)

* Update two-factor-authentication-form.blade.php

I had an issue where I couldn't scan the barcode when setting up 2FA. Determined the issue was using darkmode tailwind css styling. The Google authenticator app and VIP Access Authenticator don't pick up the barcode if it has a dark background right up against it. Add a p-4 white background resolved the issue on both apps. Propose adding this white border out of the box to prevent this issue if the user chooses a dark color adjacent to the barcode.
