privacy: reword strings in firmware security page

Tweak the text slightly to improve clarity. For example, instead of just
saying "Checks Failed" let's say "Security Checks Failed." There is
room to make the strings slightly longer.

The hardest part here was deciding what to say about the HSI-1 security
level, which is not described very well currently. I've made the largest
changes at this level.
