feat(ui): ScorePill for every grade chip

Confidence levels, the weekly score gain, target bands and lab range
flags were drawn by hand in two looks: a /15 wash without border in the
mood boards, a /10 wash with a /40 border on the correlation and trend
cards, and medium confidence was blue on one card and amber on the
next. They now render through one ScorePill (rounded, xs, soft wash,
tone success / info / warning / destructive / neutral, optional tabular
figures) with one confidence scale. The target band keeps its own
AA-tuned tokens in the shared anatomy. A structural test refuses a new
hand-rolled grade chip.

+/**
+ * A grade chip goes through `ScorePill` (`src/components/ui/score-pill.tsx`).
+ *
+ * Eleven chips that state a grade beside a reading (confidence, score gain,
+ * band, lab range) were hand-rolled in two looks: a /15 wash without border
+ * in the crosstabs, a /10 wash with a /40 border on the correlation and trend
+ * cards, and the middle confidence step was blue on one and amber on the
+ * other. This guard keeps a new copy of the chip from appearing beside the
+ * primitive.
+ *
+ * Matched: one string literal that combines the pill shape (`rounded-full`,
+ * a small padding `px-1.5|2|2.5`, `text-xs|2xs`) with a semantic tone wash
+ * (`bg-success|info|warning|destructive/10|15`). A neutral `bg-muted` chip is
+ * `TagChip`'s business, not this guard's.
+ *
+ * Not matched: a tone assembled at runtime from a map whose entries live in
+ * another literal. The guard catches the idiom, not every way to paint one.
