Allow undo of archive/unarchive
When archiving or unarchiving using the list actions, the action is immediately applied. We should include a toast with an "Undo" to allow the user to rollback this action if needed.
When undo is pressed this should:
* Restore item state
* Visually restore item in the list
* Restore item priority to the same priority number and visually restore item in the prioritized labels list
