note for reviewer: at 1st I though this line was added because I was using a different node version but it happened in v14, v16, v18 & v20. Is okay this addition?

note for reviewer: detaching the printer from the UI service makes sense. A possible scenario is to store traces for further analysis with other tools. Also changing the usage of jsonStringifyTrace makes the payload more compact so files are smaller in size

Should the trace-file "printer" be added the printers automatically if --ui is specified?

One may want to open the UI just to inspect traces from past sessions but I think you question points to the case someone starting the UI but forgetting to put the printer in place, therefore not being able to se traces in the new traces UI. I think is as good point, I'll add it in the next commit

…ic-otel-node into dluna/otlp-server-ui-optin
and also changes the web API to sort traces by date (newest 1st).
