.NET client: port stream-alarms and acknowledge-alarm + fix stream-events OCE

Adds the session-less alarm CLI subcommands. stream-alarms attaches to the gateway's central alarm feed (--filter-prefix, --max-events, --json/--jsonl); acknowledge-alarm is a unary ack (--reference required, --comment, --operator). StreamAlarmsAsync joins QueryActiveAlarmsAsync on MxGatewayClient and the transport interface; the CLI client interface, adapter, and FakeGatewayTransport follow. Also fixes the OCE bug exposed by -VerifyWrite in the cross-language e2e: StreamEventsAsync's await foreach now swallows OperationCanceledException when the supplied cancellation token is the one that fired (graceful end-of-window), and RunBatchAsync no longer excludes OCE from its outer catch — so a streaming command that hits its --timeout reports a JSON error inside its EOR-delimited record instead of killing the long-lived batch process.
