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.
