feat(tls): migrate public ingress TLS from Traefik ACME to cert-manager

Big-bang: 24 Certificates (HTTP-01, letsencrypt-prod) replace
Traefik certResolver on all prod IngressRoutes. Traefik
certificatesResolvers removed (its acme-http router hijacked
HTTP-01 for every host). AdGuard DoT shares the cert-manager
adguard-certs secret; sync CronJob retired. Dormant files
converted, n8n untouched (live-only deletion rule).

-# AdGuard TLS cert sync: copy Traefik's public certificate for dns.forust.xyz
-# (used by DNS-over-TLS on :853) from Traefik's acme.json into Secret
-# `adguard-certs`, restarting the AdGuard Deployment only when it changed.
-#
-# Why this exists: cert-manager Certificate objects cannot be used here.
-# Traefik's acme-http@internal router hijacks every HTTP-01 challenge path,
-# so the prod ClusterIssuer can never complete an order for this host.
-# Traefik itself keeps renewing the cert via its own ACME stack; this job
-# mirrors the resulting public cert/key into the secret AdGuard mounts.
-#
-# Safety properties (all enforced by the script, not by convention):
-#   * selects the PROD resolver entry only (`.letsencrypt`), never staging;
-#   * matches by main domain OR SAN list (Traefik stores the bundled cert
-#     under the router's first domain, e.g. adguard.forust.xyz);
-#   * compares sha256 hashes and patches the Secret ONLY on change;
-#   * restarts the Deployment ONLY when the Secret was patched;
-#   * exits non-zero and touches nothing when Traefik has no cert yet,
-#     when the Secret is missing, or when the payload fails PEM checks.
-#
-# Manual apply:
-#   kubectl apply -f adguardhome/k8s/cert-sync-rbac.yaml
-#   kubectl apply -f adguardhome/k8s/cert-sync.yaml
