Extend CommunicationOptionsValidator with eager bounds for the four T4 live-alarm-cache options (linger >= 0, reconcile > 0, seed concurrency 1..64, subscribers-per-site >= 1). Enforce the per-site viewer cap fail-safe in SiteAlarmLiveCacheService.Subscribe (reject excess viewers with a no-op disposable rather than growing the list or throwing into the Blazor render path). Surface two telemetry instruments on the existing ScadaBridgeTelemetry meter: an active-aggregator observable gauge and a reconnect counter, wired from the aggregator actor's PreStart/PostStop and its NodeA<->NodeB flip / reconcile-driven reopen.
