TudorandClaude Fable 5 60918da483 fix(compare): give the trend chart its own definite canvas height so the gap note can't squash it
The chart note (and the 2-row mobile chip legend) lived inside the fixed
360px/420px chartBox and competed with the canvas for it, so a longer
caption — e.g. the new KS4 gap note — shrank the mobile canvas to ~178px
and tripped the e2e >220px guard. The canvas now owns a definite height
(280px mobile / 380px desktop) with chips above and the note flowing
below at natural size, so neither can eat the plot. Verified on staging:
patched canvas renders 280px vs the squashed 178px.

The mobile chart legend stacked one school chip per line, so up to five
schools pushed the chart down and left the plot cramped. Switch the chip
row to a two-column grid; each chip fills its column and truncates its
name with an ellipsis (full names remain on the school cards and in the
tooltip). Five schools now take three rows instead of five, giving the
chart noticeably more height.

The compare chart squashed clustered schools into a thin band (y pinned
0-100) under an in-chart title + per-school legend that ate ~40% of a
300px card, leaving converging lines indistinguishable on phones.

- Auto-fit the y-axis to the data on all viewports (computeYBounds in
  lib/utils: padded + min-span for percentages, symmetric around 0 for
  progress, fitted for scores; negative pct-named trend metrics are not
  zero-clamped).
- Distinct point style per school (circle/triangle/rect/rectRot/star)
  as secondary encoding for convergence and colour-blindness.
- Mobile: drop in-chart title/legend/axis titles; add a chip row (colour
  dot + name) that doubles as tap-to-focus — highlights one school's
  line and dims the rest. Chart card 300px -> 340px, nearly all plot.
- Fix a latent colour mismatch: datasets were built from Object.entries
  whose integer-like URN keys enumerate in ascending numeric order,
  desyncing line colours from card colours; the chart now receives the
  ordered school list.
- Union years across schools instead of taking the first school's.
- Extract PerformanceChart's matchMedia pattern into hooks/useIsMobile.

Unit tests for metricKind/computeYBounds; e2e journey covers the mobile
chips and focus toggle.
