Adds www.zonadeexclusion.com to the Ingress (rules + tls hosts) so cert-manager re-issues zona-exclusion-tls covering apex + www via HTTP-01, and a Traefik redirectRegex Middleware that 301s www -> apex (ES canonical = apex). Mirrors the EN redirect-to-www-https middleware, inverted. DNS for www was fixed in Phase 1 (stale explicit A removed; now resolves via the favonia wildcard).
