feat(expenses): utlägg as an answer to "Vem betalade?" in Underlag, not a page (#2317)

An out-of-pocket purchase differs from any other receipt only in the
credit account, so the Underlag pane now asks one question for an
unmatched underlag (Företaget / Jag, privat / En anställd / Ingen ännu)
and books a privately paid receipt in place through POST
/api/expense-claims, replacing the "Andra sätt att bokföra" dropdown and
the deep link into the two-step wizard. The verifikat editor stays
reachable below as the escape hatch (BFL 5 kap 6-7 §).

The person owed surfaces in Att göra under a new Betala band, one row per
person (lib/worklist expense_payout, counted in the total and exposed to
agents through the attention resource). The Utlägg nav row is gated on
existing claims, the same hybrid gate as Körjournal, since the entry
point for a new utlägg is now the Underlag pane.
