Add random heir fallback logic in EventsWorker: Implement a new SQL query to select a random NPC heir from the same region when no children are available. Enhance error handling to log cases where no heir is found, ensuring better user feedback and maintaining character associations. Update UserCharacterWorker to utilize this new logic for heir assignment.
