Subject: [PATCH] fix: once-schedule comparison uses local time against UTC
 date (#1349)

When a timezone is configured, `now` is tz-aware local time.
The comparison stripped tzinfo with `.replace(tzinfo=None)`,
producing naive local time, but `scheduled_date` is stored as
naive UTC. For users east of UTC this causes tasks to appear
expired prematurely; for users west they linger past due time.

Use `_to_utc_naive(now)` to convert to the same reference frame.
