docs(terraform): OpenAPI callback for frontend client

[queria]

When using the OpenAPI (rapidoc) web interface,
for obtaining token it uses /openapi/oauth-receiver.html as target for callback redirect.
(As can be seen also in common/infrastructure/src/app/http.rs#L607)

While Cognito requires each callback page to be specified by full URL,
having just domain or top-level url (as in console-url) is not enough.

So this adds the openapi endpoint directly to allowed CallbackURLs for the fronted client.

Summary by Sourcery

Enhancements:

• Add the OpenAPI OAuth receiver HTML endpoint to the allowed callback URLs for the frontend Cognito user pool client in the Terraform SSO example configuration.

Reviewer's Guide

Updates the Terraform configuration for the frontend Cognito user pool client so that the OpenAPI (RapiDoc) OAuth callback URL is explicitly whitelisted, ensuring token retrieval via the /openapi/oauth-receiver.html endpoint works correctly.
