test(login): stop the backoff-guard test racing its own one-second lock

A single recordFailure() locks for BASE_MS * 2 ** 0 — exactly one second — and
the test then does a real HTTP round trip against it. On CI that round trip took
1,456 ms and the guard correctly answered 200, failing the run for a reason that
has nothing to do with what the test is about.

Five failures lock for sixteen seconds. The subject is the guard's answer while
locked out, which is unchanged.

-// viewport. Nine of nine core pages do it, so the omission has never shown.
-//
-// A module page cannot: it is handed `PublicLayout` through the UI kit
-// (MODULE_API.md §3.4) and has no way to learn about two class names that appear
-// in no contract. The Integration Kit's acceptance run built a module exactly as
-// the kit teaches and it rendered full-bleed at x=0 with the footer riding up
-// under the content — the precise failure §3.4 says the kit exists to prevent
-// ("a module page that does not look like the site it is installed in").

-// So the wrapper moves behind the component a module already has. `shell` is
-// OPT-IN and omitting it is exactly today's behaviour, which is why core's own
-// nine pages are untouched by this change — they keep their own wrapper, and a
