Clarify HammerDB KTPM scale panel title (32 threads) - #1300
The HammerDB KTPM scale panel title did not indicate the worker/thread count it measures. The PerfCI run type uses 32 workers (db_num_workers: 32 in hammerdb_data_template.yaml), so the title now says so explicitly.
dashboard.json is generated from this libsonnet file via make apply (terraform jsonnet provider). Regeneration was not run here because terraform is unavailable in this environment; run make apply in benchmark_runner/grafana/perf/ if the generated file must be refreshed in this PR.
Panel behavior and queries are unchanged; this is a display-only change.

Summary
Update timeline panel title benchmark_runner/grafana/perf/jsonnet/main.libsonnet
The title changes from “HammerDB KTPM (Scale)” to “HammerDB KTPM (Scale: avg TPM, 1-32 threads)”.
This is a title-only dashboard label change with no behavioral impact. The generated dashboard.json was not refreshed, so someone should run the regeneration step before the title appears in the deployed dashboard.

- Line 702: Update the title passed to g.panel.stateTimeline.new so it does not
label results as 32-thread throughput while the query can average across worker
counts; restore the generic “HammerDB KTPM (Scale)” title unless the query is
filtered to 32 workers.

- Around line 775-782: Update the `current_worker` terms aggregation settings so
the scale panel can show every configured worker count across the selected time
range, including counts above 10. Increase or remove the size limit as
appropriate, while preserving the worker-count grouping and existing ordering.

Avoid truncating worker counts in the scale panel.
If the selected time range includes runs with different db_min_workers settings, one VM can have more than 10 worker counts. The ascending limit can hide the 32-worker result. Adjust the grouping or limit so the panel can show all configured worker counts.

The panel plots avg(tpm)/1000 over the 1-32 thread ramp, so say that in
the title.
