fix(food): remplace le parseur PDF maison par smalot/pdfparser

Le parseur regex fait maison ne décodait pas les polices Type0/CID
avec table ToUnicode (courant sur les menus générés par des outils
pro), donc les mots-clés "PLAT CHAUD"/"GARNITURE" n'étaient jamais
reconnus et l'import échouait systématiquement sur ce type de PDF.

Ajoute aussi une correction de la reconnaissance de label insensible
aux accents (strtoupper ne gère pas les accents) et élargit la
tolérance verticale de la grille pour capter les plats sur plusieurs
lignes sans capter la ligne "Déclinaison" (alternative végé).
