Fix/logical backup job cleanup (#3111)

Browse Source 
* feat(logical-backup): add configurable job history limits and TTL

Adds three new configuration options for logical backup cronjobs:
- logical_backup_successful_jobs_history_limit (default: 3)
- logical_backup_failed_jobs_history_limit (default: 3)
- logical_backup_ttl_seconds_after_finished (default: 86400)

These options control how many completed/failed backup jobs are
retained by Kubernetes and when finished jobs are automatically
deleted. This prevents accumulation of old backup jobs and pods
in namespaces with many PostgreSQL clusters.

Also updates the CronJob comparison logic to detect changes in
these new fields and trigger reconciliation when needed.

Closes zalando/postgres-operator#1092

* add added the 3 new fieldson crd

* updated gen api
