pihole: bump image to 2026.05.0 (dnsmasq CVE security release)

Pi-hole 2026.05.0 bundles FTL v6.6.2 which imports six upstream dnsmasq
security fixes, covering all publicly disclosed CVEs against the
dnsmasq 2.92/2.93 line. Per the upstream release notes the fixes are
"minimal, self-contained changes to the embedded dnsmasq sources. No
FTL-side configuration or API changes; users should see no observable
behavior change beyond the closed vulnerabilities."

Override the chart's default image.tag in helm/pihole/values.yaml (no
chart version bump). The pihole ArgoCD app is intentionally MANUAL
sync per Viktor's call -- after merge, sync the pihole app from the
ArgoCD UI to roll the pod over.
