Fix flaky extendNames e2e tests by adding 1-day tolerance for block timestamp rounding

The strict equality checks for expiry timestamps after name extension
failed because the blockchain contract doesn't always produce an exact
365-day extension. Aligned all assertions with the tolerance pattern
already used elsewhere in the same test file.
