fix(detail): render both phases for all-through schools (Batch E)

Batch E of applying the compare-screen learnings to the school detail page —
all-through handling (point 11).

An all-through school carries both KS2 and KS4 figures in the same yearly
rows, but SchoolDetailView flipped it to isSecondary and rendered GCSE-only,
hiding the entire primary phase (SATs, phonics, KS2 trend). The Results
snapshot already gated its KS2/KS4 blocks purely on data availability, so both
already appeared there — but the section title, the trend chart, phonics, the
nav label and the history table all still assumed a single phase.

- Add an explicit `isAllThrough` flag (+ `showPrimaryContent = isPrimary ||
  isAllThrough`); pure-secondary behaviour is unchanged.
- Hero: an "All-through (primary & secondary)" meta chip for all-ages framing.
- Results section: title "SATs & GCSE Results", a combined subtitle, and
  "Primary — KS2 SATs (Year 6)" / "Secondary — GCSEs (Year 11)" sub-headings
  separating the two blocks.
- Results Over Time: render two stacked PerformanceCharts (KS2 SATs + GCSEs)
  rather than crowding both stages' series — on different scales with
  different gap stories — onto one axis. Each gets its correct England overlay.
- Phonics section + nav item now show for all-through (primary-stage metric).
- History table: an all-through column set covering both phases (RWM, Exceeding,
  Attainment 8, Progress 8, Eng & Maths 4+).
- Nav "Results" label for all-through instead of "GCSEs".

e2e: a new journey asserts an all-through school (Hessle, 137306) shows both
the KS2 and KS4 results and the All-through label, with a data-driven
precondition skip if staging data drifts.
