feat(web): make vehicle info card a collapsible accordion

Collapse the Araç Bilgileri card by default. The always-visible header now
shows an at-a-glance summary (Model, Model yılı, Motor kodu); expanding reveals
the full attribute grid, which also gains the decoded drive type (Çekiş /
"Önden çekiş") from rawData. The loading skeleton now matches the collapsed
header so there's no layout jump when data lands.
