Add the same validation logic used in the list view to the detail view: - Filter for events with measurements and op === 'pageload' - Verify score.total exists after normalization - Prevents crashes when navigating directly to invalid event URLs

Replace multiple array method passes (filter -> map -> filter -> forEach) with a single for loop that combines all validation and normalization logic. This improves performance and readability while maintaining the same functionality.

Problem
The
WebVitalsDetailcomponent crashes when navigating directly to a URL for an event that is not a valid pageload event with web vitals measurements.Root Cause
The list view filters events with three conditions:
event.measurementsexistsevent?.contexts?.trace?.op === "pageload"event.measurements["score.total"] != null(after normalization)The detail view only filtered by
event_id, then accessedmeasurements["score.fcp"].valuewithout null checks, causing a TypeError.Solution
Add the same validation logic to
WebVitalsDetail.tsxas exists inindex.tsx:measurementsANDop === "pageload"in addition toevent_idscore.totalexists after normalization
