Autoscaling schedules: reduce cold-start delays for predictable traffic

Autoscaling schedules raise the minimum number of replicas before predictable traffic arrives, reducing cold-start delays. Each schedule sets a time window plus minimum and maximum replica counts, can recur or run once, and up to 10 schedules per environment can be configured via dashboard, CLI, or Management API, with non-overlapping windows of at least five minutes sharing one timezone. When no schedule is active, the environment uses its default settings.
