landing: compact GOA alt display and all-account bank fallback

Browse source 
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.

## Live stats (in bank container)
## Live stats (central host collector · hernani systemd)
Stats are **not** computed on the laptop or host browser. A small script runs
**inside the bank container**, queries libeufin for the demo funding account
(`explorer`), and writes a public JSON file next to the landing assets.
**Primary:** user **hernani** on koopa runs `taler-landing-stats.timer`
(`scripts/taler-landing/`). That process full-scans **all bank accounts**
(except `exchange` double-count), paginates every ledger, writes
`stats.json` with **GOA alt units** (`amount_alt` / Kilo-GOA / Mega-GOA / …),
and refreshes exchange + merchant stats the same way.
```bash
# on koopa as hernani
./scripts/taler-landing/install-landing-stats-host.sh
sudo loginctl enable-linger hernani
systemctl --user start taler-landing-stats.service
```
See **`scripts/taler-landing/README.md`**.
**Fallback:** in-container `landing-stats.sh` (below) if the host timer is down.
It now also scans admin + all users (skips only `exchange`).
## Live stats (in bank container · fallback)
Stats are **not** computed in the browser. A small script can still run
**inside the bank container**, query libeufin (all accounts), and write a
public JSON file next to the landing assets.
