v1.14.0: load secrets from OpenBao at boot via @simpleworkjs/bao-conf

bin/www now runs bao-conf.init({ path: 'jump-host' }) before
require('../models'), so the OIDC clientSecret captured at require time
inside createOidcClient sees the OpenBao-merged config. Authenticates to
OpenBao with a scoped VAULT_TOKEN (policy jump-host), never the root
token; fail-soft to CONF_SECRETS if OpenBao is unreachable.
config/jump-secrets.js becomes an operator-edit seed artifact (OpenBao
authoritative). README gains a Secrets section.
