test(e2e): Add a static trace lifecycle React Router E2E app

Copies `react-router-7-framework` into `react-router-7-framework-static`, which
keeps `traceLifecycle: 'static'` and its transaction-based specs. The rest of the
React Router group moves to span streaming in the PRs above, so this copy is what
keeps the static lifecycle covered.

Also groups `collectStreamedSpans` by trace. It accumulated every envelope into a
single array, so a test asserting on one request's children could mix in spans
from an earlier page load, or have its wait satisfied by them. The predicate now
sees one trace at a time.
