internal/frontend: handle deep-linking on 404

Instead of always returning a 404 if the fullPath does not exist, check
the longest candidate module path does not exist instead. This matches
the frontend fetch logic.

For example, if a request is made to
github.com/kubernetes/client-go@v0.20.1/informers/admissionregistration/v1,
we now check if github.com/kubernetes/client-go@v0.20.1 has ever been
fetched, instead of
github.com/kubernetes/client-go/informers/admissionregistration/v1@v0.20.1
(since we know the latter is not a module).
