fix: cors preflight issue in production (#178)

### Context
- Error while creating a new space in production:
> create:1 Access to fetch at 'https://w3s.link/' from origin
'https://console.storacha.network' has been blocked by CORS policy:
Response to preflight request doesn't pass access control check:
Redirect is not allowed for a preflight request.

### Issue
- I was using the `w3s.link` as the gateway host to be authorized to
serve the space content, but the cors policy defined in the `w3s.link`
doesn't allow redirects for a preflight request.
- It doesn't happen in staging because in staging I am using the actual
gateway, and not the proxy: `freeway-staging.dag.haus`.

### Fix
- Authorize the actual production gateway instead of the proxy:
`https://freeway.dag.haus`.
