When a group_1 user hist structured-contents API endpoint, he needs to be able to do 10k API calls (like our currently available on-demand articles endpoint), so that he can easily test out the endpoint and see whether it's a fit for his product.

Acceptance criteria
As a group_1 user I'm able to make 10k API requests to structured-contents endpoint in a lifetime.

ToDo

• update access policies in the main API and infrastructure to allow access
• expand the same middleware that's applied to /v2/articles endpoint to structured-contents endpoint (we should be able to use the same httputil.Cap middleware)
• test it thoroughly in dev environment (you can reduce the threshold)

Notes
There's no need to do any UI changes or anything like that, as our structured-contents endpoint falls under On-demand API current dashboard visualization of requests left should do the job.
