FQDN Active Names Memory Pressurewarning

High cilium_fqdn_active_names or cilium_fqdn_active_ips counts indicate DNS-based policy consuming significant memory. When combined with low cilium_fqdn_gc_deletions_datadog, stale entries accumulate, causing endpoint regeneration delays and potential OOM conditions.
