Fix emulator dedup window (5m cap) and fail fast on config errors

The emulator caps DuplicateDetectionHistoryTimeWindow at 5m (PT10M was
rejected). Lower test-commands-dedup to PT5M. Also make the readiness step
fail immediately when the emulator logs a config rejection instead of
waiting the full 5-minute timeout.
