Back in 2021 this test was marked as an expected failure because default values didn't work when extending a pydantic type (#829). That was fixed not long after and the issue was closed, but the marker stayed, and the test's field-order assertion (model fields first) no longer matches the behavior covered by the sibling nested-fields test, where extension fields come first.

This updates the assertion to the actual order and drops the marker, so the test now runs for real and confirms defaults work.

Test plan:

• The updated test passes without the marker.
• Pydantic suite: 158 passed, 11 skipped, 0 xfailed (previously 157 passed, 11 skipped, 1 xfailed).
• Ruff format and checks pass.

No RELEASE.md since this is a test-only change - happy to add one if you'd like.

Summary by Sourcery

Tests:

• Enable the Pydantic field-extension default test by removing its stale expected-failure marker and aligning its field-order assertions with current behavior.
