feat(substrate): deploy cert-manager, ingress-nginx, reloader + LE staging issuers via app-of-apps — restores substrate ownership after Terraform removal

Substrate had no owner since Terraform was deleted (Pure GitOps). Adds 5 wave-0/1
Applications: cert-manager v1.21.0 (installCRDs, CP tolerations), ingress-nginx
4.15.1 (LB 192.168.1.160), reloader 2.2.14 at wave 0; LE ClusterIssuers +
*.riotpiao.com wildcard cert at wave 1 (DNS-01 via Cloudflare). Adds 3 chart
repos to AppProject sourceRepos and SOPS-encrypted cloudflare-api-token secret.
Cert starts on letsencrypt-staging; flip to prod after clean issue.
