The TelemetryClient only flushed at 50 events, so the server silently lost all queued telemetry on restart. Add startPeriodicFlush/stop methods to TelemetryClient, wire up 60s periodic flush in server initTelemetry, and flush on SIGTERM/SIGINT before exit. Co-Authored-By: Paperclip <noreply@paperclip.ing>
