feat(inference): time-travel chart data to the selected run

[adibarra]

Note

Medium Risk
Changes core benchmark fetch and SQL filtering used by the main chart; behavior is covered by new tests but wrong cutoff logic could show stale or missing points.

Overview
The inference chart can now show benchmark data as of a selected GitHub workflow run, not only the latest sweep for a day.

Backend: GET /api/v1/benchmarks accepts an optional numeric runId. SQL and JSON getLatestBenchmarks apply a run cutoff on the main chart’s date-filtered path (run_started_at ≤ selected run), while keeping rows with null timestamps and skipping the filter for exact=true GPU-comparison queries.

Frontend: Run selection is resolved before chart fetch; asOfRunId is sent only when the user picks an earlier run than the latest for the model. That forces the dated query path (not the materialized-view shortcut) and extends React Query keys so per-run views don’t collide in cache.
