Subject: [PATCH] fix(httpx): preserve sync embed data= kwarg to avoid breaking
 mock-based tests

The earlier sync_httpx_client.post() call passed data=json.dumps(data),
which downstream embedding tests assert on (e.g. tests for hosted_vllm,
jina_ai, watsonx). Switching to json=data changed the kwarg name and broke
those tests. The OCI signed_body path keeps using data=signed_body and is
unaffected.
