chore(perf): Cleanup dead Web Vitals code

[0Calories]

This PR deletes a lot of old frontend code that is no longer used in the product. Some components that are still being used have been moved from their respective directories within performance to insights/browser/webVitals/components/legacy

Deleted views:

• vitalDetail view
• transactionVitals view

The transaction vitals component is currently used actually, here's an example link https://sentry.sentry.io/performance/summary/vitals/?project=11276&query=&statsPeriod=24h&transaction=%2Finsights%2Fbackend

@DominikB2014 but how do you navigate to that page? And what advantage does this page even give us over our new web vitals module? In my opinion, it just adds to an already cluttered and confusing experience

@DominikB2014 but how do you navigate to that page?

If you go to the performance section in the sidebar, click on any frontend transaction, you should see the web vitals tab.

And what advantage does this page even give us over our new web vitals module? In my opinion, it just adds to an already cluttered and confusing experience

We original removed the old "transactionVitals" views, but we had several strong complaints that customers liked these old views. So until we have something similar in the new web vitals view, we've decided to keep it for now. There's an issue up for that

Ah thanks for the context, Dom

This issue has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you remove the label Waiting for: Community, I will leave it alone ... forever!
