Fix list name display in password upgrade notifications

- Store both listname and mlist object to preserve original listname
- Use email address listname part for display instead of real_name
- This ensures correct list identification when multiple lists share the same real_name
- Add clarifying comment about OwnerNotification sending to -owner address
