Read /opt/comfyui-api-wrapper/workflows/pyworker_benchmark.json when
neither misc/benchmark.json nor $BENCHMARK_JSON_PATH yields a usable
file. The vast.ai ComfyUI base image's convert-workflows.sh maintains
that path as a symlink to the first provisioned workflow, so on that
image the operator does not need to set BENCHMARK_JSON_PATH at all.
A set-but-broken $BENCHMARK_JSON_PATH now warns and falls through to
the well-known path instead of dropping straight to the SD1.5 fallback,
so a typo in the env var doesn't mask an otherwise-working benchmark.
