fix(e2e): stabilize canary tests for langchain version drift and anthropic timeout

Normalize invocation-parameter fields (max_tokens, model, stream,
temperature) that older @langchain/openai included alongside the
standardized ls_* metadata keys but newer versions removed. Dropping
these from the snapshot makes the wrap-langchain-js-traces canary test
stable across both the locked and latest langchain versions.

Also increase the anthropic-instrumentation scenario timeout from 90s to
150s to accommodate the additional messages.batches API calls (create,
retrieve, list, cancel) that will be exercised once the batches PR merges.
