fix: Alloy block syntax, dpkg lock wait, hitl local bind, ai-reader nodes RBAC, harness image f30af2a

- Alloy 설정 3종: rule 블록을 한 줄 쉼표 나열에서 줄바꿈 속성으로 수정(실측: k8s DaemonSet
  CrashLoopBackOff, db-replica alloy.service "expected TERMINATOR, got ,"). alloy fmt로 3종 파싱 확인.
- vm/postgres-common/alloy.sh: apt에 DPkg::Lock::Timeout=600(db-primary에서 unattended-upgrades 잠금으로 100 종료).
- vm/ai-env/compose.yaml: hitl 8081을 127.0.0.1에만 바인딩(agent는 compose 네트워크로 접근).
- workloads/rbac/ai-reader.yaml: nodes get/list/watch ClusterRole 추가(agent get_k8s(nodes) selfcheck 거부 해소).
- vm/harness/image.tag: f30af2a(POST /proposals/{token}/approve·reject 포함 러너).
