fix(tests): strip ANSI in --log-level help-visible assertion

CI's narrower terminal width forced Rich to split the flag literal across
ANSI colour escapes (`\x1b[1;36m-\x1b[0m\x1b[1;36m-log\x1b[0m\x1b[1;36m-level\x1b[0m`),
so the contiguous substring `--log-level` was not present in result.output
even though the flag is registered correctly. Strip ANSI codes before the
substring check — same pattern applied to similar Typer/Rich help-text
tests in other Python projects. No code change.
