fix(home): make Att8 bar match its numbers and separate safeguarding

Two internal-consistency fixes on the "What you'll see" mock:

- The Attainment 8 bar had drifted from the numbers beside it (fill 68%
  / line 57% vs a 54.8 score and 45.9 national avg). Restored the mock's
  original 1:1 value-to-percent mapping: fill 54.8%, national line 45.9%.
- The report card grouped "Safeguarding: Met" in the same five-point
  list as the graded areas, but safeguarding is a separate binary
  met/not-met judgement under the real framework. Moved it below the
  list behind a divider, with an outlined chip and a "separate check"
  label so it no longer reads as a graded area.

Verified with tsc --noEmit and next build.
