test(e2e): adopt webpack-dev-server's 400s test cap for cold CI runners

A multi-step browser test spent its whole 120s budget on a cold
Windows runner without any single wait hanging — first build, rebuild,
and reload each run several times slower there. dev-server runs all
its tests under a flat --test-timeout=400000; the e2e suites now use
the same cap, while the per-wait 30s timeouts keep catching real hangs.
