Suggestion: execute fetch requests in browser when in Dev about storefront-qwik-starter

1. Done - #111
2. The final error message will depend on each store (depends on what the error is), but in general, a "An error occurred, could not do XYZ" would help even if only as console.log messages. In our case, it was the attempts to fetch entities. We'd like to solve this by returning the errors object from the response.json() output in api.ts.

Thanks for your feedback.

1. this is a nice improvement, pls open a PR for that
2. which kind of error need to be exposed to the end user?
   If we have a status code we can translate it in various languages

I tried to fix #2 with the following pull request:
#112

This works so far for me locally. Let me know if it doesn't make sense. I haven't tested this thoroughly.
