fix(qa2): responsive Latest-news/FAQ at tablet + muted-text contrast sweep

- Latest-news row and FAQ grid now go 3 -> 2 -> 1 columns (added a 1024px
  tablet step); .news-card drops its brittle fixed 405.33px width and fills a
  responsive grid cell. Fixes cramped 3-across cards on 769-1024px.
- Contrast: replace #98A2B3 text color (2.58:1 on white) with the palette
  muted #667085 (~4.8:1) across 13 CSS files (31 text-color uses; borders/
  backgrounds untouched, verified none on dark backgrounds).
- Re-stamped cache-bust (v=6770822f).

Note: the ~20px-looser header top-gap at 769-1024px is left as a minor,
lower-risk follow-up (would need a coordinated multi-page padding pass).
