Per-site gRPC client for central-side streaming subscriptions to site servers. SiteStreamGrpcClient manages server-streaming calls with keepalive, converts proto events to domain types, and supports cancellation via Unsubscribe. SiteStreamGrpcClientFactory caches one client per site identifier. Includes InternalsVisibleTo for test access to conversion helpers and comprehensive unit tests for event mapping, quality/alarm-state conversion, unsubscribe behavior, and factory caching.
