Wire goa-amount.js into bank/exchange/merchant intros, deploy it with the
landings, and deepen the in-container bank stats fallback to scan all
accounts (skip only exchange) when the host timer is down.
libeufin includes default HTTPS port; demo/auto-account APIs, refresh
scripts, and landing JS now normalize hosts without :443. ensure-taler-apps
also starts merchant ui-unlock after reboot.
