The Peru localization tests were updated to match revised default accounts introduced for smoother onboarding. This helps keep automated checks aligned with the current setup and reduces false failures during validation.

Purpose: Default accounts were updated for an
improved onboarding process, which caused some
tests to be outdated. Update the tests to align
with the account changes.
