ref(trace-view): make default trace view route /traces/trace (#85378)

We are removing all the `/performance` routes, therefore we should never
end up in `/performance/traces`
1. Make default route `/traces/trace` for links to trace view
2. Change performance transaction summary to use `/traces/trace`
