refactor(storefront): Migrate page to new routing

[poi33]

Fix for #1748
Migrate all pages to app/ routing
Migrate some components to new routing structure

[Barsnes]

Thanks for the PR! ❤️
I looks like you forgot to rename the pages under grunnleggende

The GitHubLink.tsx link also seems to be throwing an error, but the path here would also need to be updated to route/page.mdx

We also need to add meta data, so we get titles for the pages.
This was previously done with a <Meta /> component, but in the app router we need to export it:

export const metadata = {
  title: '...',
  description: '...',
};

I'd like to move over to layout.tsx files as well, but it works now and can always be done later on. We also have the issue of props that layouts need 🤔

Otherwise everything looks great 🎯

Thanks a lot! ❤️
There are a few minor bugs when building, but nothing I can't fix after a merge.
The biggest part of moving over to the app router is done, and routing seems to be working perferctly!

I'll approve this and solve the remaining build errors in the next branch, thanks a lot! 😄

@Barsnes I had some trouble with the sizes. Tried to match it to the latest build off i think it was the react package. Tried to keep it in sync.

You might not have built it locally? We are using the workspace package, and not from npm.
A lot of good work either way!
