🐛 fix icon coverage tracker against new dada API shape (#117)

dada is deprecating currenciesOrder.currenciesIds (returned empty,
removal in a later release). Reconstruct the ranked ledger ID list
from currenciesOrder.metaCurrencyIds and each meta-currency's
assetsIds map. Verified locally: 400 / 410 covered, 10 missing.
