SEC-27: DashboardSnapshot.GatewayStatus was hardcoded Healthy. It is now the aggregate HealthCheckService status, evaluated once per snapshot tick (2s bound, zero-wait gate) and cached for GetSnapshot; Unknown before the first evaluation, on failure, or without a health service. The startup-static EffectiveGatewayConfiguration is JsonIgnore'd on the snapshot, so /hubs/snapshot ticks carry only volatile state. The hub sends it once per connection (ConfigurationUpdated) and serves GetConfiguration(). Snapshot broadcasts are time-bounded (1s) so one slow client cannot delay ticks. StatusBadge maps Unhealthy to Bad.
