Add a toast for liquidation notification

[JonRay15]

The Chore

Add a toast when you have been liquidated.

Continuation of work in #6019

Tasks

• [ ] Add toast
• [ ] Make sure the toast message contains all the nice info
• [ ] Make sure the toast pops up if the liquidation happened while you were away
• [ ] Probably the toast will need to pop up every time you open console and your last trade is still the network close out, even if you've seen it before ... unless we can keep in local storage ... but I doont know that we need to
• [ ] Once you have made a new trade the toast should not appear again next time you open console
