This controller handles path requests that didn't match an existing route,

including the main Plug.Static for the / root path.

To handle this situation, we'll check if the requested resource exists as

a file under the blog content repo folder, by querying the Blog genserve.

If it exists, we'll redirect to the blog content static path under /_
|

Otherwise, we'll return 404 not found.
