feat(endo/init): updated codebase with _document.js.

[tgrecojs]

• added _document.js file to load @endo/init
  • next.js' beforeInteractive strategy nextjs.org/docs: no beforeInteractive outside docoument
  • Optimally load third party scripts using next script
• updated tsconfig.json so that it would build properly. (i'm not sure if this is a side-effect from how I was importing a component. npm run build works properly already then disregard this change.)
  • resolved typescript compilation error for non-relative paths Resolving TypeScript Errors in Next.js

@samsiegart I apologize in advance if there are some issues with the format of my code. I was mainly focused on getting the _document.js file together and being able to provide you with some additional input.

I'm not completely over the hill yet but I think there is some solid progress made. For one, i'm almost certain that the approach that needs to be taken is to use beforeInteractive with _document.js. This change makes use of this approach, and everything seems to render properly. There is only one issue - @endo/init doesn't seem to be doing anything?

Below is a screen grab of the application booting up. You can see that @endo/init is the first script loaded out of the bunch, which is the expected behavior of beforeInteractive. But it doesn't seem to actually be calling lockdown.
