refactor(scraping): job PENDING dès le POST HTTP, handler sans Doctrine

- ScrapingJob: mangaId/chapterNumber/sourceId optionnels (nullable) pour
  permettre la création en PENDING sans lookup DB dans le StateProcessor
- ScrapeChapter: ajoute jobId (pré-généré par le StateProcessor)
- ScrapeChapterStateProcessor: crée et persiste le job PENDING avant
  dispatch; injecte JobRepositoryInterface uniquement
- ScrapeChapterHandler: supprime EntityManagerInterface, beginTransaction/
  commit/rollback; charge le job existant via jobId, complete() sur succès
  seulement, fail() si toutes les sources échouent
- ScrapeChapterHandlerTest: pré-crée le job, passe jobId dans la commande,
  supprime le mock EntityManagerInterface
- ScrapeChapterTest: accès aux messages via static InMemoryMessageBus,
  vérifie la présence du jobId dans la commande dispatchée
