[brunomenezes]

📄 Context

Here are the node-runners private node management page changes on colour, skin tones and fonts in Dark mode to comply with the new Cartesi brand. The application's structure did not change, only the look and feel.

PS: Refer to the parent of this issue for references. PS²: Don't worry about the header and footer, because that is addressed in a separate issue #62
