Ajout section Explorer sous le diaporama /photo et factorisation HeroViewport

La page /photo affiche maintenant une flèche de scroll invitant à découvrir
une section de navigation avec les catégories et le fil photo en dessous du
diaporama, avec un dégradé progressif entre les deux.

Le pattern "hero viewport + scroll indicator" est factorisé dans un composant
HeroViewport réutilisable, utilisé par /photo (mode transparent), les albums
de catégories et les posts du fil photo.
