Replaces `redis.redis:6379` with `redis-master.redis:6379` in all 11 dependency.kyverno.io/wait-for annotations across 8 stacks, plus one docs comment in the Kyverno module. These annotations drive DNS-only `nc -z` init-container readiness checks — zero RW risk. Both hostnames resolve, so there is no wait-for failure window during the rolling re-apply. Closes: code-otr
