fix(python): resolve native job types in API docs (#4170)

Native job metadata types report `builtins` as their module, so Griffe
cannot resolve the public `lancedb.job` re-exports and the Python API
reference build fails. Set the PyO3 module metadata for `JobInfo`,
`JobDescription`, and `JobFailureInfo`, and cover import resolution in
the existing package metadata tests.

Reproduced the failure and validated the fix with the docs CI toolchain
(`griffe==0.49.0`, `mkdocstrings==0.25.2`, and
`mkdocstrings-python==1.10.9`). After rebuilding the native extension,
the full `PYTHONPATH=. mkdocs build` succeeds and all three classes and
their public members appear in the generated reference.
