Convert parametrize argvalues to lists for pytest 10

[faisalsardi-dev]

Summary

What:

Two warnings show up when running python -Im pytest. They're about a pytest 10 deprecation: iterators passed to parametrize won't be accepted anymore.

How:

Wrap the itertools.product() calls passed to pytest.mark.parametrize() in list().

Why:

product() returns a one-shot iterator. pytest 9 accepts it but emits PytestRemovedIn10Warning, and pytest 10 will require a Collection.

Converting to a list or tuple is the fix documented by pytest:
https://docs.pytest.org/en/stable/deprecations.html#parametrize-iterators

Same 948 tests collected before and after, so the parametrization didn't change.

Most of the diff is re-indentation caused by the added list() wrapper. git diff -w shows the actual change is two lines per call site.

Verification:

Running python -Im pytest shows the two PytestRemovedIn10Warnings are gone, reducing the warning count from 2 to 0.

I skipped the changelog since this only touches tests.
