polish(school-detail): align hero stat numbers on a shared baseline

The three at-a-glance stats were misaligned — the serif "Outstanding" tile
sat noticeably above the "70%" and "64%" numerals because the serif variant
used a smaller font. That pushed its label row ("INSPECTED NOVEMBER 2023")
up too, breaking the horizontal rhythm across the row.

- Give .heroStatNumber and .heroStatNumberSerif a shared min-height tied
  to the largest clamp value, plus display: flex; align-items: flex-end.
  Content bottom-aligns inside the box, so every stat's label sits at the
  same Y regardless of how tall the actual glyph is.
- Bump the serif variant up slightly (1.75rem → 2.25rem clamp) so it
  feels closer in weight to the numerals while still leaving room for
  longer words like "Requires Improvement".
