test: tolerate minute-aligned scheduled wakeups

[yuaanlin]

Summary

• allow the scheduled-wakeup live audit to wait through the full minute-alignment window
• keep a small buffer for the autonomous model turn to complete
• raise the Vitest case timeout accordingly

ScheduleWakeup(delaySeconds=60) is persisted as a minute-aligned cron entry. Depending on where scheduling lands within a minute, delivery can take close to two minutes. The previous 75-second predicate timeout can therefore fail even though the idle ACP stream delivers the wakeup correctly. I reproduced both outcomes against current main: one run timed out at 75 seconds, while a second run delivered LIVE_WAKE_OK through the idle ACP stream.
