Znuny-PrimarySecondary

This add-on introduces a primary/secondary relationship for tickets (formerly known as Master/Slave). It is particularly useful for major incidents or mass inquiries where many users report the same issue. By marking one ticket as 'Primary' and others as 'Secondary', agents can manage the communication and resolution from a single point. Actions on the primary ticket, such as adding notes or changing states, are automatically synchronized to the secondary tickets. When the primary ticket is closed, all secondary tickets can be closed automatically with a predefined state and note, significantly reducing manual effort.
