Bringing all components to one figma page

[jannick-ux]

Instead of having a separate page for each component, we could restructure the file to reduce pages and make designer's experience better. Selecting all components to a dedicated page, as well as the icons and the foundations on their own would lead to a much smaller sidebar in figma.
Another option to structure the components could be sub-categories (similar to CoreUI).
Figma performance need to be checked before.
