[python] pin remaining unpinned dependencies in python docker images

[gnufede]

Motivation

Follow-up to kowalski/python-pin-anyio-4-15: pin all remaining unpinned transitive and direct dependencies across parametric, anthropic, openai, google_genai, fastapi, and tornado Docker images to prevent breakage from future package releases.

Changes

Pinned transitive deps: h11, idna, protobuf, grpcio, googleapis-common-protos, Deprecated, wrapt, backoff, importlib-metadata.
Pinned direct deps: PyYAML, requests, pycryptodome, python-multipart, jinja2, psycopg2-binary, itsdangerous, tornado, httpx.

Workflow

1. ⚠️ Create your PR as draft ⚠️
2. Work on you PR until the CI passes
3. Mark it as ready for review
   • Test logic is modified? -> Get a review from RFC owner.
   • Framework is modified, or non obvious usage of it -> get a review from R&P team

🚀 Once your PR is reviewed and the CI green, you can merge it!

Reviewer checklist

• Anything but tests/ or manifests/ is modified ? I have the approval from R&P team
• A docker base image is modified?
  • the relevant build-XXX-image label is present
• A scenario is added, removed or renamed?
  • Get a review from R&P team
