feat(m28+m29+m30): ACME ARI, email digest, and Helm chart

M28: ACME Renewal Information (RFC 9702) — CA-directed renewal timing with cert ID computation, directory endpoint discovery, graceful degradation for non-ARI CAs. 19 tests. M29: Email notifier wiring + scheduled certificate digest — SMTP connector bridged to service layer via NotifierAdapter, DigestService with HTML email template, 7th scheduler loop (24h), digest preview/send API endpoints and GUI card. 21 tests. M30: Production-ready Helm chart — server Deployment, PostgreSQL StatefulSet, agent DaemonSet, ConfigMaps, Secrets, Ingress, security contexts, health probes, example values for dev/prod/ACME scenarios. Also: OpenAPI spec updates, MCP tool additions, CI helm-lint job, documentation updates across 5 doc files and README. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
