chore : bump version to v1.9.41

Même pattern que la fix Piece (003e419) : helper ensureCustomFieldExists()
qui force l'init du proxy lazy et catch EntityNotFoundException dans
MachineStructureController::normalizeCustomFieldValues() et
CustomFieldValueController::normalizeCustomFieldValue(). Les CFV pointant
vers un CustomField supprimé sont silencieusement skippés au lieu de
crasher la vue machine entière.
