feat(rankings,metrics): score visible on phones; definitions usable everywhere (P2.2, P2.3)
Rankings mobile: the metric value — the point of the page — sat behind
a sideways swipe at 390px. The Area column now folds into a subline
under the school name, leaving Rank | School | Value to fit the
viewport with no horizontal scroll.

Rankings default metric becomes 'expected standard' (rwm_expected_pct);
'higher standard' stays available but no longer frames every school's
headline number in the terms parents least understand.

MetricTooltip was hover-only and display:none on phones — the mobile-
primary audience had zero access to the Attainment 8 / Progress 8 /
EBacc definitions. It is now a real button: tap/click/keyboard
toggleable with outside-click and Escape dismissal, 24px target,
shown at all viewports.
