Update email campaign schedule (global settings)
Deprecated
PATCH
Replaces the campaign schedule (sending window, pace, tracking). The campaign must not be RUNNING or ARCHIVED. Extra validation beyond the schema: minInterval <= maxInterval, start <= end, dailyLimit >= dailyContact. Changing days/start/end/tracking rewrites each step version's per-day schedule. New integrations should use the multichannel /advanced campaign endpoints instead.
