feat(recipes): associe ingredients, quantites et ustensiles aux techniques detectees

Etend le pipeline de detection de techniques (tech-step-matcher.ts) pour
resoudre, par clause, les metadonnees qui accompagnent une technique
detectee :

- Ingredients : nouvelle fonction findIngredientMentions (ingredient-matcher.ts)
  qui scanne le texte d'une clause contre le catalogue Ingredient existant
  (reutilise INGREDIENT_LABELS_FR/EN deja utilise par matchIngredientName),
  avec extraction best-effort de la quantite+unite immediatement avant la
  mention.
- Ustensiles : nouveau catalogue Utensil (Prisma) + second PhraseMatcher
  cote service Python (intent_service/utensil_vocabulary.py), independant
  du textcat des techniques (pas d'interpretation necessaire pour un
  ustensile). POST /v1/process distingue desormais chaque entite via un
  champ kind (technique|utensil).
- Persistance : deux nouvelles tables StepTechStepIngredient/
  StepTechStepUtensil, liees a StepTechStep par sa cle composite
  (stepId, order), peuplees au moment du matching (recipe.service.ts) et
  exposees via StepTechStepView (packages/shared).

Aucune analyse syntaxique ajoutee (le parser spaCy reste exclu du
pipeline) : l'association se fait par appartenance a la clause deja
calculee par splitIntoClauses.
