Support terminal interactive mode when running a node server

[autodidaddict]

Proposed change

When we run node up, we should be able to specify that we want to run that in interactive mode. The default should continue to operate the way it does now where it's just emitting logs to stdout (e.g. the production-ready mode).

We should be able to opt into interactive mode (e.g. with --interactive flag on node up). This would give us a full screen tui that lets us navigate around the various control operations for that specific node, as well as view the logs and other important information.

Use case

When developing workloads and functions for Nex, I want to be able to have more easy interaction with my development node server. I imagine myself being able to use arrow keys to navigate through the list of namespaces in use and the running workloads within those, and to be able to view and tweak whatever configuration I might like.
This lets me have my code in one window and an easy and fun to use terminal window for the node.

Note that we've decided to have it be nex tui and not tied to a running node process, so that it will essentially be a tui version of everything you can do with the CLI
