ci(cold-db-smoke): shrink to cold-boot + admin bootstrap only

Drop steps 5-7 (issue/renew/revoke + audit row assertion). They
covered functional API behavior (cert lifecycle) which the warm-DB
integration test suite under 'Go Test with Coverage' already
covers thoroughly. The cold-DB smoke's unique value is catching
the bug class only a true cold boot can surface — config
validation gaps, non-idempotent migrations, env-var-wiring gaps
in the demo compose. Today's run found three real master bugs of
that class (6d0f774 DEMO_MODE_ACK, 910097e migration 000043
idempotency, 58b1441 bootstrap-token interpolation); cert
lifecycle is not in that bug class.

Steps that remain (proven to fire on real bugs today):
  1. docker compose down -v --remove-orphans
  2. docker compose up -d (cold boot)
  3. wait for postgres + certctl-server + certctl-agent healthy
  4. force-recreate certctl-server with CERTCTL_BOOTSTRAP_TOKEN +
     POST /api/v1/auth/bootstrap — proves the full migration
     ladder ran cleanly on a warm DB second-boot AND that the
     day-0 admin path works.

Steps dropped:
  5. issuing test cert via POST /api/v1/certificates
     — required team_id + renewal_policy_id + issuer_id from
     the seeded demo data; the original payload was speculative
     and would have needed maintenance whenever the seed shape
     changes. Functional cert-issue coverage already in the
     integration suite.
  6. renewing via POST /api/v1/certificates/{id}/renew
     — same: functional renewal coverage in the integration
     suite.
  7. revoking + asserting audit row presence
     — same: handler tests cover audit emission.

Wall-clock cap tightened from 15min to 10min (the dropped steps
were the slowest; 4 steps fit comfortably in ~7-8min cold).
