Accessing the web dashboard throws `nucleus Error: ENOENT: no such file or directory, open 'SOME-DIR/nucleus-server/public_out/index.html'` error

Accessing the web dashboard after running `yarn dev` throws `nucleus Error: ENOENT: no such file or directory, open 'SOME-DIR/nucleus-server/public_out/index.html'` error. The `public_out` is not a real directory.

Changing all occurences of `public_out` to `public` raises this error:
```
nucleus Unhandled error: / +7s
nucleus Error: ENOENT: no such file or directory, open 'SOME-DIRnucleus-server/public/index.html' +0ms
```

How do I fix this?

Start by reproducing the failure with `yarn dev` and trace how the dashboard resolves `public_out/index.html`, then compare that path with the attempted `public/index.html` path. The issue is done when the web dashboard opens without an ENOENT error and the expected asset directory is consistently used.
