Feuilles de poste : ajouter la photo des bénévoles affectés

Vignette carrée (14 mm, proportions préservées) à côté du nom de chaque
bénévole affecté, à côté de son téléphone — case vide si le bénévole n'a
pas de photo. Complète l'affichage déjà en place sur l'écran référent et
l'écran bénévole (étape 22).
