bank: API for auto-created personal accounts (balance zero)
Add GET /intro/auto-account.json on the bank helper (demo-withdraw-api): public registration with generated username/password, balance starts GOA:0, credentials returned once for the client to display. Nginx proxies the new path; install-demo-withdraw-api.sh installs the location. This is separate from the shared explorer demo withdraw.
