Add "jinx prevention" to tickets

These notifications are made and updated every 10 seconds to the user, and if no update is sent in around a minute, the notification will be cleared from the database.

Normal users will not see these notifications, only staff members will.

This requires a hit on `create-all.py`... though if a different solution, such as blinkers, is more suitable for this, let me know.
