feat(dashboard): restyle Mijn aanvragen / Wat moet ik regelen as a CIBG keuzelijst

Both sections offer a set of choices the user picks between to proceed, matching
designsystem.cibg.nl/componenten/keuzelijst rather than the "aanvragen" row pattern
("Wat wilt u doen?" keeps that look — it's a static nav list, not a choice list).

- New shared/ui molecules: choice-list (heading + keuzelijst__list, wired via
  aria-labelledby per CIBG's a11y guidance) and choice-link (one keuzelijst__link
  choice; routerLink, imperative-clickable, or a plain non-interactive block).
- choice-link's non-interactive block needed a `--static` modifier: CIBG's
  `.keuzelijst__link:after`/`:hover`/`:focus` key off the bare class (keuzelijst
  assumes every item is a link), unlike `.applications li a::after` which is scoped
  to the anchor — without it, a non-actionable aanvraag row inherited a chevron and
  hover accent it shouldn't have.
- task-list.component.ts now composes choice-list/choice-link internally; public
  API unchanged except a new required `listHeading` input (the heading moves inside
  the list for the aria-labelledby link, so dashboard.page.ts stops rendering it
  separately — same fix applied to "Mijn aanvragen").
- aanvraag-block.component.ts moves from application-link to choice-link, combining
  its separate status/subtitle text into one instructions paragraph (keuzelijst has
  no cta field — the row itself is the action). Only a resumable Concept renders as
  a real choice; InBehandeling/Goedgekeurd/Afgewezen stay non-interactive, unchanged
  from before.

Verified: lint/check:tokens/build green, 178 tests pass, build-storybook succeeds,
and manually driven end-to-end (dashboard renders both sections as keuzelijst cards,
confirmed via screenshot that non-actionable rows have no chevron after the fix).
