Fix lingering Python 3.14 “upstream gated” skips in IBM Watsonx tests

  • src/backend/tests/unit/base/models/test_model_utils.py:12-17 and src/bundles/ibm/tests/test_watsonx_embeddings.py:11-14 still pytest.skip(..., allow_module_level=True) on ImportError with comments referencing python_version<'3.14' gating; this can mask real 3.14 importability regressions.
  • Update these tests to assert the newly supported 3.14 import path (and remove/adjust the outdated gating rationale/skip logic) in line with the dependency pins in src/backend/base/pyproject.toml:99-100.
  • Ensure src/bundles/ibm/README.md:29-38 also no longer documents the old <3.14 gating behavior.

In `@src/backend/base/pyproject.toml` around lines 99 - 100, Tests currently skip
on ImportError with legacy python_version<'3.14' gating which can hide real
import regressions; update the two test modules (test_model_utils.py and
test_watsonx_embeddings.py) to remove the pytest.skip(...,
allow_module_level=True) import-based skip and instead directly import/assert
the IBM Watsonx client/package import path that should now succeed per the
pinned deps ("ibm-watsonx-ai" and "langchain-ibm"); remove or update the inline
comments referencing "<3.14" gating and replace with a simple import/assert
check (or an explicit failure message) so failures surface, and similarly edit
the IBM bundle README section describing `<3.14` gating to reflect the new
supported 3.14 importability.
