containment: hardcap admin API publish gate + outbox self-sufficient pool

- hardcap PATCH /admin/articles/:id → PUBLISHED now stages into
  outbound_drafts (channel hardcap) instead of publishing, when
  HARDCAP_PUBLISH_MODE=draft (default). Fail-closed. Verified E2E:
  PATCH on a QUEUED article returned {staged:true, draft_id:7} and the
  article stayed QUEUED.
- bitcoinhotels.org: audited — frontend only (Next.js), no publishing
  path; nothing to contain.
- outbox.mjs: self-sufficient pool (createRequire from
  /srv/cayce-core/node_modules/pg — hosts may lack pg; found by the
  promo simulation which now works end-to-end).
- runtime/hardcap/admin.ts: versioned copy of the patched route
  (hardcap-backend itself is not a git repo).
- deploy.sh: hardcap env wiring (HARDCAP_PUBLISH_MODE, IDENTITY_PATH,
  CAYCE_PGURL appended server-side).

🔴 UNRELATED CRITICAL FINDING (needs operator decision, not patched
without approval): hardcap admin API has NO authentication and binds
*:3001 — reachable from the public internet (HTTP 200 from outside,
including DELETE /admin/articles/all). Recommend: auth middleware +
bind 127.0.0.1 + firewall, plus rotation of credentials that appeared
in journald (hardcap DB role DSN leaked via a psql error line during
testing — fixed in the same patch, but journald retains it).
