fix(rankings): long metric labels wrap instead of widening the table

Table auto-layout sizes columns by unwrapped header text, so labels like
'Reading, Writing & Maths Combined Higher %' pushed the value column —
and the table — past the viewport. The label now renders inside a block
span capped at 110px (84px on phones), forcing multiline and keeping the
table fully in view at any metric.
