uiserver - sentry - high traces in production

[leafty]

In production, the uiserver created an enormous Sentry transaction with 100k+ spans over 2 weeks -> https://renku.sentry.io/explore/traces/trace/dcd91dd0263b4aba9111fdbceeabbbc8/?cursor=0%3A50%3A0&guidedStep=1&node=span-bdfa04934039f11f&project=4509044015169616&source=traces&statsPeriod=30d&targetId=b3bc360fa74c7feb&timestamp=1772781425.

It seems that the uiserver was sending the traces for polling sessions with the websocket. This should be investigated and fixed if possible -> is it possible to limit the transaction duration (e.g. 5 minutes) and then start a new one?
