Backup frequency silently reduced from hourly to daily

High Severity

The postgres-insights cluster's backup schedule was changed from hourly (0 */1 * * *) to daily (0 0 * * *) when switching from incremental to differential. The first cluster (postgres-data) correctly preserved its original daily schedule during the type change, but this second cluster's cron expression appears to have been copy-pasted from the first, silently reducing backup frequency from 24×/day to 1×/day. This significantly increases the recovery point objective (RPO) for the insights database.
