Provide a runnable TUI demo interface via `textual-web` for users to try against the Anomaly license

For users to be able to try the TUI without having to install anything it would be cool if we can provide a web accessible version. [`textual-web`](https://github.com/Textualize/textual-web) is designed to this and is currently in `beta`

## Technical consideration

We should first run a demo to see what infrastructure we need to run a tui application (e.g do we need to run a deamon or process of some sort?)

~Ideally we should be able to run this on a service like `vercel` or `railway` to minimise any infrastructure management overhead.~

From what I can see that `textual-web` runs a proxy that is accessible via their web service (pending further investigation)

```
~/.local/bin/textual-web --run "gallagher.tui:main"
```

The demo license is provide for Anomaly to use, so we would have to consider some of rate limiting or even a way for the user to limit interaction. This might even involve a mechanism to reset the virtual machine running our command centre to a `good known` state every 24 hours?

Ensure that the API key is never exposed as part of the demonstration.

## Other thoughts

This would definitely be a very good demonstration of the #9 and #27 features without the user having to set anything up.
