Notification rows in the history page need the document title. Added findTitlesByIds(Collection<UUID>) to DocumentService (one query via a new JPQL projection on DocumentRepository). NotificationService.getNotifications() now fetches all titles for the page in a single extra query and maps them into the DTO. documentTitle is null when the document has been deleted.
