UX: Improve second factor UI (#9526)

This will make a few minor improvements to the second factor user interface. Highlights include: - Using the site's title to prefix the backup code filename. If non-ascii characters are detected, then prefix "discourse" instead. - Add icons and change the text on some of the buttons for better clarity and consistency - Add an education link to the security key modal
