fix: keuzelijst rows become the <li> (RD-37)

app-choice-link rendered a component host between the keuzelijst <ul>
and its <li>. This broke the axe list/listitem rule for assistive
technology. Five story suppressions named WP-11 as the fix, but WP-11
closed with no open ticket left to own the defect.

choice-link now uses selector: 'li[app-choice-link]', the same
attribute-host pattern as application-link. The host carries the
keuzelijst__list-item class; the template drops its own <li>.
Position: relative stays on .keuzelijst__link so the stretched-link
overlay still resolves against the card, not the host.

aanvraag-block needed no component change: it renders a CIBG melding,
never an <li>. Only its story wrapped it in a <ul>, which is what axe
rejected. The wrapper is removed, and the four non-Concept stories are
deleted — the component's template only renders for status Concept, so
they rendered nothing.

All five a11y: { disable: true } suppressions are gone, with no
replacement. atomic-design.mdx now records that both molecules are the
<li>, kept separate for the vendored CSS they bind, not for list
semantics.

npm run ci --full passes, axe included.
