Upgrade components folder structure

[blushi]

Is your request related to a problem? Please describe.
Currently, we use a mixture of atomic design and feature/context-based structured components, which can be confusing and makes it harder to look for components.

Describe the solution you'd like
We decided to leave atomic design out in favor of a more simple structure:

• controls
• components
• pages (only applicable in web-marketplace and web-www): in particular in web-marketplace we should restructure the current pages folder following Next.js app router structure: https://nextjs.org/docs/app/building-your-application/routing#roles-of-folders-and-files https://nextjs.org/docs/app/building-your-application/routing/defining-routes which should ease any future migration to Next.js

Each component should now have its own folder
