Fix cached-page 500s and flaky smoke/API tests

- terms/privacy/community-guidelines views accessed the cached page as an
  object ($page->title), but cachedPage() returns an array, causing a 500
  whenever a custom Page row existed. Switch to array access.
- PublicRouteSmokeTest: enable open_registration before hitting /register,
  which 404s by default when registration is disabled.
- Api/AccountTest: derive sanctum.stateful domain from app.url instead of
  hardcoding pixelfed.test, so the first-party auth test is environment
  independent.
