feat(recipes): permet d'associer ingredients/ustensiles a une correction de technique

Etend le flux de correction existant (TechStepCorrectionPopover) pour que
l'utilisateur associe lui-meme des ingredients (avec quantite/unite) et
des ustensiles a la technique qu'il corrige, avec le meme marquage
source: "manual" que la technique elle-meme.

Backend :
- submitTechStepCorrectionSchema (packages/shared) accepte des tableaux
  ingredients/utensils optionnels, chacun avec son propre span [start,end)
  selectionne par l'utilisateur. Omis = ne touche pas aux metadonnees
  existantes ; tableau (meme vide) = remplace tout ce qui existait sur
  cette occurrence (auto ET manuel precedent - decision validee avec
  l'utilisateur).
- applyManualCorrection (recipe-tech-step-correction.service.ts) ecrit
  les nouvelles lignes StepTechStepIngredient/StepTechStepUtensil apres
  avoir vide celles de l'occurrence via deleteMany - meme chemin de code
  que ce soit une creation ou une mise a jour de la technique.
- Nouveaux asserts d'existence (ingredient/unite/ustensile) + validation
  de span, nouveau code d'erreur UTENSIL_NOT_FOUND.
- source ajoute a StepTechStepIngredientView/StepTechStepUtensilView
  (le calque manquait ce que la colonne DB portait deja).

Frontend :
- TechStepCorrectionPopover passe d'un clic = soumission immediate a un
  flux selection-puis-confirmation, avec deux nouvelles sections
  Ingredients/Ustensiles pre-remplies avec l'existant.
- Ajouter un ingredient/ustensile demande une selection de texte dediee
  dans la description encore visible (StepDescription geree via un
  nouvel etat pendingSpanRequest/resolvedMetadataSpan) - pas de raccourci
  sur le span de la correction elle-meme.
- Nouveau CatalogSearchPicker.tsx, plus leger que IngredientPicker pour
  ce contexte de popover, reutilise pour les deux catalogues.
- getUtensils() ajoute a apiClient.

Tests : nouveaux cas Mocha (attache/remplace/omission/validations) dans
recipe-tech-step-correction.test.ts, TechStepCorrectionPopover.cy.tsx
etendu avec le nouveau flux, recipes.ts (e2e) ajuste au clic Valider
supplementaire.
