fix(recipes): une étape peut porter une séquence de tech steps

Corrige le modèle de données suite à une review sur la PR #34 :
"Dans une poêle chaude, faire chauffer une noix de beurre" combine
deux techniques (preheat + melt), or Step.techStepId ne pouvait en
porter qu'une seule (FK simple nullable).

- Step.techStepId (FK simple) remplacé par StepTechStep, une table de
  jointure ordonnée (stepId, techStepId, order) — @@id([stepId,
  order]) garantit une séquence propre par étape.
- tech-step-matcher.ts : matchTechStep(...) → number|null devient
  matchTechSteps(...) → number[]. Nouvel algorithme : chaque mapping
  qui matche devient un candidat avec sa position dans le texte ; on
  garde le meilleur candidat par technique (poids, puis position),
  on résout les chevauchements entre techniques différentes par poids
  décroissant (ex: "cuire au four" ne garde que `bake`, pas `cook` en
  plus), puis on trie le résultat par ordre d'apparition dans le
  texte — une séquence qui se lit dans le même ordre que l'instruction.
- Ajout de la technique "melt" (faire fondre) au catalogue, pour
  pouvoir tester le cas concret du commentaire de review de bout en
  bout (préchauffer + faire fondre).
- recipe.service.ts : câble StepTechStep via un create imbriqué à la
  place du champ scalaire.

Tests étendus dans tech-step-matcher.test.ts (séquences non
chevauchantes, résolution de chevauchement combinée à une technique
distincte, etc.) et recipe.test.ts (nouveau test de bout en bout avec
deux techniques dans une même étape). 133 tests passent.
