Footer on bank/exchange/merchant shows Landing vN, last content change
time, and a linkified git commit. Start at v42; bump with
scripts/taler-landing/stamp-landing-version.sh --bump.
Ship goa-amount.js inside each landing tree, add an inline fallback when
the asset is not yet deployed, keep CHF free of GOA unit names, fix
exchange amount_full wiring, and add test-landing-stats.sh (local + live).
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.
