style: aligne le balayage de re-extraction sur le design system

La page et le panneau de differences avaient ete ecrits avant que main ne pose
un design system unique : classes Tailwind brutes, et surtout un detail
depliable reste sur fond clair alors que son contenu venait de passer en sombre.

Reprend les classes du systeme (page, card, table, btn, badge, subcard,
empty-state, spinner) et ramene le detail au fond sombre. Les avertissements de
reecriture passent en amber-400, illisibles jusqu'ici sur fond sombre.
