Refactor event handling for character death: Updated the EventsWorker to ensure only player characters are notified of sudden child deaths, while NPCs are excluded. Adjusted health update logic to prevent player characters from reaching zero health due to accidents or illnesses. Enhanced SQL queries to filter characters based on user ID, improving clarity and functionality.
