feat(recipes): toggles afficher/masquer allergènes et régimes dans le picker

Deux boutons icône en bout de la barre de recherche de l'IngredientPicker
(régimes/feuille, allergènes/triangle), même pattern bouton-icône +
état actif que FavoriteStarButton. Préférence d'affichage locale au
picker (non persistée) — n'affecte pas quels ingrédients apparaissent,
seulement si leurs badges allergènes/régimes sont visibles sur les
cartes. Nouvelle icône AllergenIcon dans nav-icons.tsx, réutilise
DietPreferencesIcon existante.
