scripts: refresh scan_packages allowlist baseline (#7078)

New releases of huggingface-hub (1.23.0) and openai (2.45.0) shifted or
added polling loops that the C2 polling/beaconing check flags, failing
all three pip scan-packages shards (studio 1, hf-stack 1, extras 3 new
CRITICAL findings) org-wide including on main.

Regenerated with scan_packages.py --write-baseline per CI shard (same
shard-to-requirements mapping and --with-deps as security-audit.yml)
and merged. All entries were manually reviewed at the resolved versions:

- huggingface-hub hf_api.py: create_repo 409-concurrency retry loop
  body changed in 1.23.0; refreshed evidence hash. The loop POSTs to
  the canonical Hub endpoint and retries only on a specific conflict
  error. Benign client retry.
- openai beta/threads/runs/runs.py: create_and_poll run-status helper
  refactored in 2.45.0 (Assistants deprecation annotations); refreshed
  evidence hash. Documented polling helper against api.openai.com.
- openai beta/responses/responses.py: new beta websocket client whose
  __aiter__ yields server events until the connection closes. New
  entry; standard event-stream iterator, not beaconing.
- openai resources/responses/responses.py: evidence line number
  refreshed only, hash unchanged.

The two dropped entries are the pre-refactor hashes of the same two
loops above; they no longer occur at the resolved versions. Verified
locally: all three shards exit 0 with 0 unsuppressed CRITICAL/HIGH
(hf-stack 120, studio 151, extras 99 suppressed).
