chore(lint): trier les imports, sauf la facade des modeles

Active la regle isort (I) de ruff. 45 fichiers reordonnes, aucun
changement de comportement : la suite passe avant comme apres.

app/models/__init__.py en est exclu. Ses imports sont ranges en onze
couches commentees qui decrivent le graphe de dependances ; trier par
ordre alphabetique laisse chaque titre au-dessus d un import qu il ne
decrit pas, et ce fichier n a qu un role, etre lu.

Commit isole, comme le formatage : un diff de brassage ne doit pas
servir de couverture a un changement de comportement.
