fix(e2e): Explicitly disable Spotlight in react-router-7-lazy-routes test

The PR adds automatic Spotlight detection via environment variables. This test
is about transaction timing behavior, not Spotlight functionality. Explicitly
disabling Spotlight prevents it from being auto-enabled, which was causing the
transaction to finish prematurely (0.006s instead of 5+ seconds).
