fix(project) : permet de choisir un workflow à la création + filet par défaut

La création de projet échouait : `Project.workflow` est obligatoire mais
n'était jamais fourni (formulaire frontend, MCP create-project), tout POST
/api/projects partait en erreur de validation/contrainte NOT NULL.

- ProjectDefaultWorkflowListener (prePersist) : assigne le workflow par
  défaut quand aucun n'est fourni, couvrant API Platform, API brute et MCP.
- retrait de l'Assert\NotNull sur Project::workflow (la validation tournait
  avant le flush et empêchait le filet) ; la contrainte DB reste le garde-fou.
- CreateProjectTool (MCP) : paramètre optionnel workflowId.
- ProjectDrawer : sélecteur Workflow en création, pré-rempli sur le défaut,
  IRI envoyée dans le payload.
- tests fonctionnels : création avec et sans workflow.
