Fixes#1173. invoices.total_sek stays NULL when the Riksbanken rate
fetch fails at creation, and every `total_sek || total` fallback then
treated a raw foreign amount as kronor:
- lib/calendar/utils: new invoiceSekAmount() returns null for
unconverted non-SEK invoices; period summaries and day totals skip
them and PeriodSummary exposes unconvertedCount. PaymentSummaryCard
shows a one-line note when invoices were excluded; CalendarDayView
renders each invoice in its own currency instead.
- Deadlines page: the overdue attn sum now skips unconverted FX
invoices and appends "(+N i utlandsk valuta)" instead of adding EUR
into a kr total.
- Supplier-invoice payment toast formats the amount with the invoice's
currency (key drops its hardcoded " kr" in both locales).
- AR aging drill-down row labels Betalt with the invoice currency,
mirroring the outstanding cell.
- BankFileColumnMappingStep: comment pinning why SEK is safe there
(generic-csv hardcodes it).
