feat(insights): hit-rate breakdown by detector kind

Browse Source 
Adds a "By detector kind" breakdown to the anomaly outcome report + Insights page,
answering "which directional detector actually wins?". Only directional kinds
(SuspensionFlip, SteamMove) resolve to hit/miss, so the breakdown naturally shows
just those — mirrors the existing by-sport / by-severity bucketers and rendering.

- AnomalyOutcomeReport.ByKind + EvaluateAnomalyOutcomesUseCase.BuildKindBuckets
  (keyed OutcomeBucketKeys.KindPrefix + enum name); threaded through the insights VM/service.
- Insights page: new section + BucketRenderKind.Kind label case (resolves the enum name
  to the Anomaly.Kind.* resx); en/ru section heading.
- 2 tests: empty-report ByKind + directional-kind grouping.
