shankar0123 ce34cb96a1 feat(cert-export): typed audit-action constants + has_private_key + cipher detail (Phase 7)
Production hardening II Phase 7 — typify the cert-export audit
emission. The pre-Phase-7 audit log carried inline strings
("export_pem" / "export_pkcs12"); this commit adds typed
constants alongside via the split-emit pattern so operators get
both back-compat with existing log analysers AND a stable typed
grep target.

NEW internal/service/export_audit_actions.go:
  - AuditActionCertExportPEM = "cert_export_pem"
  - AuditActionCertExportPEMWithKey = "cert_export_pem_with_key"
    (reserved for future bundle that adds key-bearing export; not
    emitted in V2)
  - AuditActionCertExportPKCS12 = "cert_export_pkcs12"
  - AuditActionCertExportFailed = "cert_export_failed"
  - PKCS12CipherModernAES256 = "AES-256-CBC-PBE2-SHA256" pinned
    string for the cipher detail (drift catches a future go-pkcs12
    default change)

Detail enrichment on both emission sites:
  - has_private_key (bool, V2 always false — cert-only export is
    the only V2 path; key-bearing export deferred to future bundle)
  - actor_kind ("user")
  - cipher (PKCS12 only — pinned to PKCS12CipherModernAES256)

Split-emit pattern: each export emits BOTH the legacy bare action
code AND the typed constant. Mirrors est.go::processEnrollment which
emits both "est_simple_enroll" + "est_simple_enroll_success".
Existing audit-log analysers that match by exact string "export_pem"
keep working; new operator alerts can target the typed constant.

Pre-commit verification: go build ./... clean; go test -short
-count=1 green for service/.
