Wrap Recommendations (scenario tabs + cards), Budget, and Timeline in
<details> accordions. Recommendations stays open by default; Budget and
Timeline collapse closed so the post-quiz page doesn't dump everything at
once. The panel becomes the white-paint container — inner .budget-meter,
.timeline, and .scenario-tabs drop their own box treatment to avoid a
nested-card look. revealSections() now staggers the panel wrappers
instead of the inner containers, and added en/de strings for the panel
headers.
