* fix(import): per-currency totals and row currency in bank-file preview
Fixes#1170. ParsedBankTransaction carries a per-row currency (Wise
emits genuinely mixed rows; camt.053 reads Ccy per entry), but the
preview and confirm steps formatted every amount as kr and rendered
parser-level income/expense totals that sum across currencies.
Adds summarizeByCurrency() (income positive / expenses negative, ore
rounding, SEK default) and renders one total line per currency on both
steps; preview table rows format amount and balance with the row's own
currency.

* fix(import): use roundOre from lib/money (antipattern ratchet)
The naive Math.round(x * 100) / 100 form is blocked by check:guards
(subtly wrong on exact-half values); lib/money.roundOre is canonical.
