C-001 scope expansion: tighten parallel POST /api/v1/certificates call sites to six-field contract

Problem:
a53a4b8 closed C-001 at the handler boundary by tightening the
ValidateRequired contract on POST /api/v1/certificates to require six
fields: name, common_name, renewal_policy_id, issuer_id, owner_id,
team_id. (Correction re-derived from source: the handler
ValidateRequired calls on owner_id/team_id/renewal_policy_id were
actually installed in 3287e17 under M-002/M-003/M-006 auth unification
— a53a4b8's commit message overstates scope.) Post-audit on
2026-04-18 found three parallel call sites still shipping
three-to-four-field payloads that the newly strict handler would
reject with HTTP 400:
  - GUI: OnboardingWizard CertificateStep (common_name + sans +
    issuer_id + environment only)
  - CLI: certctl-cli import (common_name + issuer_id + status only;
    no required-flag gating)
  - Tests: deploy/test/qa_test.go Part03 positive paths

Scope:
Bring every POST /api/v1/certificates caller to six-field parity. No
handler changes — the contract is authoritative; the callers must
conform.

Implementation:

  GUI — OnboardingWizard CertificateStep expansion:
    web/src/pages/OnboardingWizard.tsx adds name/owner_id/team_id/
    renewal_policy_id state. React Query hooks for getOwners/
    getTeams/getPolicies use per_page: '500' to populate dropdowns
    without pagination-driven truncation. Payload ships all six
    required fields plus sans/certificate_profile_id/environment.
    nextDisabled gate enforces all six before the Continue button
    activates.

  CLI — ImportCertificates rewrite:
    internal/cli/client.go rewrites ImportCertificates with
    flag.NewFlagSet("import", flag.ContinueOnError). Required flags:
    --owner-id, --team-id, --renewal-policy-id, --issuer-id. Optional:
    --name-template (default {cn}, templated via strings.ReplaceAll
    against cert.Subject.CommonName), --environment (default
    imported). Missing required flags fail pre-HTTP with a clear
    error. Request map ships all six required fields plus sans/
    environment/status/optional serial_number.
    cmd/cli/main.go — usage string updated to document the new
    required/optional flags.

  Tests — qa_test.go Part03 positive paths:
    deploy/test/qa_test.go Part03 Create_Minimal and Create_Full
    updated to include all six fields. Uses seed_demo.sql-supplied IDs
    (o-alice, t-platform, rp-standard) — docker-compose.demo.yml is
    the run context. C-001 explanatory comment added above
    Create_Minimal so future readers understand why the minimal
    payload is no longer minimal.

  MCP parity:
    Verified no-op. internal/mcp/types.go:28 CreateCertificateInput
    already declares all six fields; internal/mcp/tools.go:102
    forwards the typed struct unchanged.

Verification:

  Go CLI regression tests (internal/cli/client_test.go):
    * TestClient_ImportCertificates_MissingRequiredFlags — 5 subtests,
      one per missing required flag, confirms flag.ContinueOnError
      rejects with non-nil error before any HTTP call is attempted.
    * TestClient_ImportCertificates_MissingPositionalArgs — confirms
      the "usage: import <file>" error path when no PEM file is
      supplied after the flags.
    * TestClient_ImportCertificates_SixFieldPayload — uses httptest
      to decode the POST body and assert all six required fields
      plus sans/environment are present on the wire.

  Frontend regression test (web/src/api/client.test.ts):
    'createCertificate accepts and transmits all six required fields'
    pins the wire shape for both GUI call sites (OnboardingWizard
    CertificateStep + CertificatesPage CreateCertificateModal). If
    either UI surface accidentally drops a field, this assertion
    fails in CI rather than surfacing as a 400 at runtime.

  Grep-based call-site sweep:
    Enumerated every POST /api/v1/certificates create caller. Four
    total: OnboardingWizard, CertificatesPage, MCP tools, CLI import.
    All four now ship six-field payloads. Claim path
    (internal/service/discovery.go) updates existing rows and does
    not POST. EST/SCEP handlers invoke internal
    certService.CreateVersion, not the public API. Negative-path
    tests (qa_test.go:1085/1267/1274/1288/1298) remain valid: they
    assert 400/non-500 on oversized/malformed/missing-CN/UTF-8/empty
    bodies, and these properties still hold under the stricter
    handler.

  Static gates:
    go build ./..., go vet ./..., go test ./internal/cli/..., and
    cd web && npm run test deferred to operator pre-push — the Go
    toolchain is not available in the session sandbox. Grep-based
    verification confirms the syntactic shape of every changed file.

Residual:
None. Every POST /api/v1/certificates call site now conforms to the
six-field contract; the wire shape is pinned by both Go and
TypeScript regression tests.
