Security audit: refresh scan baselines for current dependency set (#7362)

The pip scan-packages extras shard has been red on main because openai
2.47.0 changed the code inside five previously baselined findings, so
their evidence hashes no longer matched the allowlist. The hf-stack
shard was about to go red the same way: unsloth-zoo 2026.7.5 changed
two baselined test files.

All seven reopened findings were re-verified against the exact resolved
archives before re-baselining:

- openai/_base_client.py: while True in SyncPage.iter_pages, the
  pagination iterator.
- openai/auth/_workload.py: Azure IMDS and GCP metadata token
  providers for the documented workload identity federation feature.
- openai/resources/{beta/responses,realtime,responses}: while True in
  websocket __aiter__ event loops; the loop bodies gained reconnect
  handling in 2.47.0, which is what shifted the hashes.
- unsloth-zoo tests/test_vision_collator_audio.py: asserts that an
  inline /tmp/a.wav path is passed through by the audio collator.
- unsloth-zoo tests/test_gemma4_forced_float32_ple_dtype.py:
  compile()/exec() of the project's own generated Gemma4 PLE cast
  helper source in tests.

No existing entries were removed. All three shards now exit 0 locally
against the same requirement sets CI uses.
