correction: credential-forward + unified graph; activate SOPS (author-first)

Operator directive: don't diverge architecture to avoid asking for credentials;
provision them upfront via SOPS and keep the existing (unified) graph.

Roadmap reconciliation: Phase 2 = Network/Storage/TLS/DNS/Ingress, so
cert-manager/externaldns/gateway (the credential-gated pieces) ARE Phase 2;
monitoring is Phase 4. Earlier A2/rollout scope was inverted by credential-avoidance.

Reverts (credential-driven): remove clusters/dev/rollout/ + the $patch:delete's;
restore unified base graph (dev = ../base + cluster-vars + SOPS decryption,
R-ENV-02 intact); restore monitoring files (Phase 4). Kept non-credential
improvements: tofu for_each/rejoin, Kyverno parametrization + webhook excludes.

platform/kustomization.yaml now phased (single shared list): Phase-2 set =
kyverno, cilium, longhorn, cert-manager, externaldns, gateway; later components
commented with phase markers.

SOPS activated: .sops.yaml at repo root; bootstrap/sops/secret-templates/*.yaml.example
for all secrets (cloudflare x2, grafana, alertmanager-smtp, keycloak, oauth2-proxy, pia);
bootstrap/sops/CREDENTIALS.md checklist; pre-wired commented cloudflare-api-token lines
in cert-manager + externaldns; filled non-secret ACME email. Agents never touch real
secret values (operator encrypts).

Validated: kubectl kustomize dev(unified)/prod/platform(Phase-2 only), templates inert,
make -C ci gate PASS.
