fix(SW-236): properly handle expired token in webviews

Trying out a new pattern for errors in data fetching.

Next.js is not a fan of throwing errors. Instead it recommends returning
different shapes for each state. Ref:
https://nextjs.org/docs/app/building-your-application/routing/error-handling#handling-expected-errors-from-server-components

It requires some more detailing and a bit more refactoring in non webview part,
but it is a start. This webview specific implementation should not break web.
