feat(worklist): the next Skatteverket payment with bankgiro, OCR and due date under Att göra on Hem (#2435)

Part (a) of #2187. A twelfth worklist category, skattekonto_payment_due:
the earliest upcoming skattekonto charge whose sum exceeds the last synced
saldo, computed once in lib/worklist (server-side twin of the /skattekonto
page's Nästa dragning math) and rendered as one Betala row on Hem with the
shortfall, bankgiro 5050-1055, the OCR reference and the due date.

The row appears only when money has to move: a saldo that covers the charge
yields nothing, and no upcoming charge yields nothing. Ignored rows take
part, since Skatteverket draws them regardless of our flag. Without a
balance snapshot the full charge is the amount. Without an org number the
row keeps its bankgiro and date and drops the OCR.

No table, route or migration: /api/worklist/counts picks the category up
through getWorklistCounts, and Hem passes the computed row into the same
options wave as the expense payouts.

Part (b), a betalfil for the skattekonto payment, stays a follow-up: the
existing payment-file route is AGI-scoped.
