Feature/sc 39874/fix mongo production sync

[yodem]

Description

Adds pod eviction protection to the MongoDB sync cronjob to prevent Cluster Autoscaler from evicting pods during job execution.

Code Changes

helm-chart/sefaria/templates/cronjob/sync-mongo-production-data.yaml

• Added cluster-autoscaler.kubernetes.io/safe-to-evict: "false" annotation to the pod template metadata
• Annotation is placed under spec.jobTemplate.spec.template.metadata.annotations (not on the CronJob's own metadata)
• Ensures pods created by this CronJob will not be evicted by Cluster Autoscaler while the MongoDB restore operation is running

Notes

• The annotation prevents Cluster Autoscaler from evicting pods during long-running MongoDB restore operations, ensuring jobs complete successfully
• The annotation is correctly placed on the Pod template (not the CronJob metadata), so it applies to all pods created by this CronJob
• This is particularly important for restore operations that may take significant time to complete
