feat: M15b — OCSP responder, DER CRL, short-lived exemption, revocation GUI

Backend: - Embedded OCSP responder: GET /api/v1/ocsp/{issuer_id}/{serial} returns signed OCSP responses (good/revoked/unknown) using CA key - DER-encoded X.509 CRL: GET /api/v1/crl/{issuer_id} returns proper DER CRL signed by issuing CA with 24h validity window - Short-lived cert exemption: certs with profile TTL < 1 hour skip CRL/OCSP (expiry is sufficient revocation for ephemeral workloads) - Extended issuer connector interface with GenerateCRL and SignOCSPResponse - Local CA implements full CRL/OCSP signing; ACME and step-ca return appropriate "use native endpoint" errors - IssuerConnectorAdapter bridges new methods between layers Frontend: - Revoke button on certificate detail page with RFC 5280 reason modal - Revocation banner with reason display and timestamp - Revocation status indicators in lifecycle section - "Revoked" filter option in certificates list - API client: revokeCertificate() function and Certificate type extensions Tests: ~31 new tests across connector, service, handler, and adapter layers Docs: milestones renumbered (M13-M14, M16-M18), M15b marked complete Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
