Fixes#1172. The Fakturor sheet's Totalt/Betalt/Utestående columns are
invoice-original currency (the sheet carries a Valuta column and a
separate SEK-converted Utestående (SEK) column), yet used the
kr-suffixed currency format, so a EUR invoice rendered "1 000,00 kr"
beside Valuta=EUR. They now use the suffix-free decimalColumn added in
#1166; the SEK column and the SEK-converted aging sheet keep kr. The
supplier-ledger xlsx was checked: its buckets are SEK-converted via
resolveSekAmount, so kr is correct there.
