Preserve Jobflow settings swaps during serialization

[Andrew-S-Rosen]

Summary

• store Jobflow settings_swap values in the serialized job document instead of only in a function closure
• execute the original stripped function under the requested temporary settings on the worker
• add a regression test covering a tuple-valued ESPRESSO_PARALLEL_CMD through a Monty/Jobflow serialization round-trip

Root cause

Jobflow serializes a job callable by its module and name. The existing settings wrapper captured settings_swap in a local closure, so deserializing the job remotely resolved the original module-level function and discarded the captured settings. This caused values such as the "-npool 2" suffix to be lost.

Impact

Redecorated Jobflow jobs now retain temporary quacc settings when submitted to a remote worker, including tuple-valued Espresso parallel commands.

Validation

• python -m pytest tests/jobflow -q (24 passed)
• python -m ruff check src/quacc/wflow_tools/decorators.py tests/jobflow/test_customizers.py
• python -m ruff format --check src/quacc/wflow_tools/decorators.py tests/jobflow/test_customizers.py

Closes #2501
