fix(devops): bypass OpenBao base entrypoint to prevent dev-mode flags

The base openbao image's docker-entrypoint.sh injects -dev-root-token-id
and -dev-listen-address flags when it sees 'server' as $1, causing the
server to exit immediately (code 0). Override entrypoint with dumb-init
and call bao directly to avoid the dev-mode flag injection.
