Christian Manivong 571d9abb5f style: ruff format and the lint rules of the driver standard
Mechanical: ruff format, and ruff check --fix with the rule set every NAPALM
driver uses (E, F, I, UP, B at line length 100, Python 3.10). What ruff
cannot fix comes in the next commit.

"""Unit tests for OPNsense ping / ping_sweep — no real device required.
The OPNsense ping API is job-based: a job is created (``set``), started
(``start``), produces statistics that are read back via ``search_jobs``, and
has to be stopped and removed again. These tests drive that whole lifecycle
against a fake ``_get`` / ``_post``.
