Subject: [PATCH] fix(k8s): use ClusterIP service and FQDN for Valkey
 connection

Changed Valkey service from headless to ClusterIP and updated
REDIS_HOST to use full FQDN for more reliable DNS resolution.

Changes:
- valkey-service.yaml: Changed from headless (clusterIP: None) to ClusterIP
- deployment.yaml: Changed REDIS_HOST from "valkey" to "valkey.towerops.svc.cluster.local"

This ensures stable ClusterIP and explicit DNS resolution for Redis connections.
