feat(dashboard): snapshot carries the day's dose state, score and verdict inputs

The snapshot's fast phase gains a medsToday block — active count,
today's scheduled/taken/skipped tally after the idempotent projection,
and the earliest server-computed next due across active medications —
and the warm phase derives a compact health score from the coverage
map and graded blood-pressure windows the extras build already holds.
A pure verdict resolver ranks the day's single highlighted item over
nine rungs from an overdue dose down to a quiet-day fallback, with
fixed crisis floors for the blood-pressure rung and timezone-correct
day checks. The layout grows a heroVisible flag riding the stored
widgets JSON, the iOS summary route adopts the shared dose-state
builder with an unchanged wire shape, and the new sub-blocks report
their build time alongside the existing snapshot timings.
