feat(ops): pipeline-health dashboard

- Add a /health ops page: snapshot freshness (last-capture-at, colour-coded), 24h vs total snapshots + anomalies, events tracked, sports covered, and the four worker on/off states. Nav entry under System; localized en+ru. - New IPipelineHealthService + ISnapshotRepository.GetLatestCapturedAtAsync (max CapturedAt via indexed ORDER BY/LIMIT 1), with a real-SQLite round-trip test.
