feat(anomalies): filter the feed by detector kind

Adds a detector-kind chip row to the anomaly feed (SuspensionFlip / SteamMove /
SuspensionFreeze / OverroundCompression), multi-select like the sport filter — so
with four detectors live you can slice the feed to a single signal type. The kind
set lives on AnomalyFilter and filters in-memory alongside severity/sport, persisted
via AnomalyBrowsingState like the other filters.

- AnomalyFilter.Kinds + AnomalyBrowsingService in-memory Where clause; feed chip
  row + ToggleKind/KindLabel; en/ru resx (Anomaly.Filter.Kind).
- 2 tests: kind-filtered subset + no-filter returns all kinds.
