Intercept httpx2 in the Microsoft Bot's Anthropic endpoint test - #761

Conversation
anthropic 1.x sends through httpx2 rather than httpx. The test patched httpx.AsyncHTTPTransport, so with the newest SDK its request reached the real Anthropic API and failed with 401, breaking main's CI. It now patches httpx2.AsyncHTTPTransport, as the AG2 Bot's tests already do.

anthropic1.12.1 now depends onhttpx2and sends throughhttpx2.AsyncHTTPTransport. The test patchedhttpx.AsyncHTTPTransport, so the request escaped the test harness. It now patcheshttpx2, matchingagent-ag2's tests. Test-only.Verified on fresh installs of each Bot's requirements:
agent-microsoft10 pass (the failing case reproduced before the change),agent-pydantic-ai13 pass.
