NetworkAdaptiveCardContentProvider class

Card source that fetches JSON over HTTP(S).

The url is untrusted, so it is validated against uriPolicy before any request (blocking SSRF to loopback/private hosts) and the response body is capped by fetchPolicy. Pass an optional client to inject HTTP in tests.
