feat(dashboard): show today's dose tally on the medication hero ring

The MED_COMPLIANCE hero ring carried the pooled 7-day adherence
percentage — a mystery number next to today-focused scores. It now
answers the question the hero poses: how many of today's doses are
done. The resolver reads takenToday/scheduledToday off the snapshot's
own medsToday block (one shared builder call, no second tally); score
stays the rounded 0..100 progress for wire compatibility and a new
additive doses field carries the taken/scheduled pair. No dose
scheduled today means no ring, and the band is progress semantics —
green once everything is taken, yellow while doses remain, never red
(a pending morning dose is not an alert state).

The web ring renders the tally (1/3) with a doses label over the ring
system's constant green arc — the same green family the compliance
surfaces in Insights paint — instead of a band gradient; the derived
rings keep their exact insights hues. ScoreRing gains documented
valueText/ariaLabel overrides for tally-shaped centres. OpenAPI
regenerated; labels land in all six locales.
