test(litebe): make the retire test deterministic under the change-gate

The change-gated refresh worker only runs `balance` on a full-refresh
cycle, so testLiteWalletControllerRetire could no longer reliably park
the worker inside a blocked `balance` (it passed only by timing). Bump
the fake scanned height to force a full-refresh cycle, which enters the
now-blocked `balance` deterministically.
