Provide method for UI console to issue its actions

Maybe just putting the background (dnode) object on the global, so that the UI's own behaviors can be triggered by the console.

This would allow console-based invocation of any UI feature that is having problems.

The idea came from how the SNX token recently broke all other tokens loading. A simple command to tell users to run in the console would be a much cleaner workaround than asking them to reinstall.

Downsides:

• Hard to imagine the future benefits, it's a general purpose bug workaround feature.
• Adding an object to global scope violates all kinds of POLA, so I would only even consider doing this in the UI. We once did something like this in the background then realized it meant every dep had easy access to the whole operation, so that should be off the table.

Benefits:

• Pretty easy to do, easy workarounds in the future.

This could also end up allowing phishers to convince users to run console commands and exfiltrate keys or other sensitive data.. This sounds too dangerous for us to consider, and I don't think we generally need it. We can make a button in the UI for anything an action can do.
