feat(portal): 139 create server side portal

[Tzal3x]

Create a nextjs server that acts as a server-side walrus-sites portal. It works by combining a middleware for preprocessing the requests, and a root endpoint (defined inroute.ts) that actually contains the logic as the service worker did.

The middleware has the following role:

1. To handle requests like http://<name>.walrus.site/path/to/file/ without throwing an error. Explanation: if you don't define a route on nextjs, the default logic is to throw an error because the /path/to/file endpoint does not exist.
2. To delegate the whole request (including the subnames) to the route.ts in order to fetch the site resources. By default the subnames are removed from the hostname in nextjs.

In summary, the middleware is just a delegator and an error-preventer of the original url.

💁‍♂️ Review tip: the PR consists of 2 commits. I would suggest reviewing commit by commit and not the whole PR altogether.

Base skeleton is there. It doesn't work yet, something wrong happens with the url parsing.

Issues:

• Even though I'm hitting http://docs.localhost:3000/, when the url is parsed from the splitUrl in domain_parsing.ts, it seens only as if I'm hitting http://localhost:3000/. Subdomains are ignored.
• Trying to access a path that doesn't exist in nextjs results in an error e.g http://docs.localhost:3000/non_existing.html Middleware wouldn't have that problem. How could I bypass this?

Another article to consider: nextjs wildcard subdomains

⚠️ Looks like subdomains don't work with safari.

i.e. http://docs.localhost:3000/ returns this error: Safari can't find server. Safari can't find the server docs.localhost

⚠️ There seems to be an infinite loop occurring when I'm running an instance of the server's production build (pnpm run start). It doesn't occur on development mode (pnpm run dev).

Sample output:

🎉 Fixed - I created this post that explains it.

did you add the settings to .editorconfig? if so, can you commit them?

@giac-mysten I actually just removed the prettierrc file because it was redundant after I compared them.
