Feature: UI NPM package

Hello.

I'm planning to build a custom view for SBA and I was reading about it in https://docs.spring-boot-admin.com/4.0.2/docs/samples/sample-custom-ui (I found no other more detailed sources).

I was wondering if it could be possible to package what's referenced in there as well as any other reusable piece of code (e.g.: components) in an npm package that we could add as dev dependency in order to have a better development experience.

Ideally I would like to be able to run npm run dev and have the UI fully rendered, but that's maybe too much.

Having already the - allow me the wrong term - types properly referenced so that TS and ESLint don't scream all the time would already be great.
