feat(eval): filterable item metadata and dataset runs for the Experiments tab

The filter bar matches on metadata only — not on input and not on the item id — so a dataset seeded with repo/pr in `input` alone could not be sliced by repo at all. Every facet worth filtering on is now a flat primitive in `metadata`: repo, owner, repo_name, pr, head_sha, finding_count, has_findings, max_severity, reviews_run and the review timestamp both ways. `owner` is split out because a filter on the joined repo matches one repo, never a whole org, and `max_severity` is "none" rather than absent because an absent key matches no filter. `eval_experiment.py` links reviews that already ran into a dataset run, one run per model, so the Experiments tab is populated without re-running the reviewer. One trace per (run, item), the most recent: a PR re-reviewed on every push has many traces and a run is one output per input. It posts to the deprecated /api/public/dataset-run-items — the notice exempts self-hosted v3 from the cutoff date and the pilot is stdlib-only by design. Revisit at v4.
