False positive: "Missing cross-site request forgery token validation" in C# API for endpoint with no cookie/session tokens

**Description of the false positive**

We are using a .NET 10 Api and since commit https://github.com/github/codeql/commit/5bb31afc834f53d5ea719d782744ff9c7ab70fc2 we get a false positive on a server -> server endpoint where we have a ApiKey in the header with no tokens or cookies.

Is it possible to extend the check to look if cookie/token authentication is used instead of a ApiKey?

**Code samples or links to source code**

```
public class Controller()
{

[HttpPost()]
public string Execute()
{
return "test";
}

```

Start by reviewing commit 5bb31afc834f53d5ea719d782744ff9c7ab70fc0 and the C# API example in this issue to understand why the finding applies. Locate the query entry point and its existing tests, then verify that API-key-only server-to-server endpoints are not flagged while endpoints using cookie or token authentication still are.
