Added an Important note in custom_resource_explained.md to clarify that serviceTemplates[].spec is not merged with operator defaults.

For ClickHouseKeeperInstallation replica host services (replicaServiceTemplate), spec.publishNotReadyAddresses: true must be set when overriding spec; otherwise Kubernetes won’t publish DNS for not-ready Keeper pods, and Keeper peers can’t discover each other during initial Raft bootstrap, which can lead to quorum/readiness deadlock and startup failures.
