fix(home): correct education/Ofsted claims on the landing page

Homepage marketing content had drifted from both the current
education regime and the app's own school pages. An expert accuracy
review surfaced five issues (3 critical, 2 high):

- Ofsted card showed a single "OUTSTANDING" word-grade. Overall grades
  were abolished (Sept 2024) and inspections now produce a report card
  on a five-point scale (from Nov 2025). Rebuilt the card as a report
  card with per-area ratings + stand-alone safeguarding, matching what
  CompareOfsted actually renders on a school page.
- Attainment 8 "National avg 50.2" was wrong; the real 2024/25 figure
  is 45.9. Corrected the benchmark and the illustrative school value.
- Compare mock featured a KS2 "Reading progress" score, but KS2
  progress isn't published for 2023/24 or 2024/25 (no post-COVID KS1
  baseline). Swapped for Higher standard (RWM), which is published.
- Editorial called it "UK school performance data"; the data is
  England-only. Now matches the hero and page metadata.
- Softened the "40-page inspection report" exaggeration.

Landing-page copy isn't covered by e2e journeys, so no test changes.
Verified with tsc --noEmit and next build.
