[feat]: Add an interactive terminal/shell to the UI

[dr-bonez]

goal is to allow the user to run shell commands from the embassy dashboard. additional scoping needed to determine where to put this to limit users accidentally performing unwanted changes.

Only allow to access when dev tools activated.

Haha xD

Seems we could limit this to just embassy-cli commands.

Or at least to the start9 user rather than root.

Depends on what the goal of this feature is. What would we like the user to be able to do from the UI?

Seems this was opened to replace the SSH over Tor feature request - when I opened that I was picturing full SSH access.

If we implement full SSH access, we will want this feature to be very hidden.

The below could be leveraged or looked into as a way to run this.

This may not be a desirable solution to use, as the code is a bit dated, but it at least paints a picture of what I have in my head as to what is going on here.
