Feat base for node editor

[c0rtexR]

Context and Justification 🌍

This PR introduces react-flow as the starting point for building out the editor functionality in the @data-river/editor package. The integration is basic for now and serves as a foundation for further development. Additionally, it adds react-flow to the dashboard in the client project (specifically in dashboard.tsx) within the Remix setup. Lastly, I included default Prettier and VSCode formatting settings to maintain consistency in code style across the project.

Modifications 🔧

1. Added react-flow as an editor in the @data-river/editor package.
