[2026-07-resubmission] Add guest browsing flow with App Attest session for App Review resubmission

Adds a pre-login public store locator (guest session via DeviceCheck/App Attest, keychain-backed token storage) so the app no longer forces sign-in before showing any content, plus updated support URL metadata.
