fix(insights): match HealthScore card height to the hero column

The HealthScore card paints 75-110 px shorter than the action+prompts
column to its left at md+ — the bottom edge of the card lands a full
chip-row above the suggested-prompts strip's last entry. The two
columns sit in a flex row but the row was anchoring children with
`items-start`, which lets the right column collapse to its content
height even though the left column's chip-strip wraps to two or three
rows on desktop.

The fix is two-sided:

- The hero row flips from `items-start` to `items-stretch` whenever the
  HealthScore panel mounts. The class only applies on the conditional
  branch so the no-score layout keeps the same vertical rhythm it had.

- The card wrapper opts into the stretched shell with `flex h-full
  flex-col`; the existing inner content block becomes `flex-1 flex
  flex-col gap-3` and the disclaimer footer gets `mt-auto`. The score
  number and sub-bars stay anchored at the top, the disclaimer pins to
  the bottom, and the recovered vertical space sits quietly between
  the provenance accordion and the disclaimer footer rather than
  spilling under the disclaimer line.

FB-H3 — the "Wochenbericht erstellen" button and the WeeklyReportBanner
were both retired in the R3b weekly-report scope-reduction pass; the
hero action row is already Coach-only and nothing in this commit
revisits that surface.

Tests pin the row's `md:items-stretch` / `lg:items-stretch` classes,
the wrapper's `h-full flex flex-col` opt-in, and the disclaimer's
`mt-auto` anchor — DOM-class assertions, no brittle pixel-height
checks. Tests on the no-score branch keep the older `items-start`
absence pinned so a future refactor can't blanket-apply the stretch
contract on layouts that have nothing to stretch toward.
