Confidence values are not separated

[MarcoSteinke]

In the frontend the display of the object's confidence values is not done right. It is only iteration-wise and I did not come to think about it yet. It is a quite simple problem I think

Detected objects are also not separated.

The following methods from https://github.com/MarcoSteinke/Security-Cam/blob/main/src/Detection/Detection.js seem to be causing a bug.

getObjectLabels() {
  return objects.map(object => object.label).join(',');
}

getObjectConfidences() {
  return objects.map(object => object.confidence.toFixed(2)).join(',');
}
