refactor : simplification globale (vague 1 + 2)

- ActorProfileResolver : service unique partage par AbstractAuditSubscriber, EntityVersionService et ModelTypeCategoryConversionService (3 implementations dupliquees+divergentes)
- corrige un bug latent : EntityVersionService restoraitsans le fallback Security::getUser, loggant actor=null hors session
- machine-clone : clonage des contextFieldValues integre dans cloneComponentLinks/clonePieceLinks, supprime cloneContextFieldValues et son find() en boucle
- helpers extraits : serializeProductSlots (EntityVersionService), updateModelTypeCategory (ModelTypeCategoryConversionService)
- supprime collectCollectionUpdate() vide + ses appels (AbstractAuditSubscriber)
- useMachineDetailData : retire debug ref couplee a isEditMode, componentTypeLabelMap/pieceTypeLabelMap jamais consommes, double assignation machine.productLinks
- PieceItem : retire l'init pieceData dans onMounted (deja couvert par reactive() et le watcher)
