fix(expenses): review follow-ups from #2317 (#2326)

- The Utlägg nav row is computed server-side, so the first booked claim
  now refreshes the App Router tree instead of staying hidden until a
  full reload.
- The dialog's default date is the local calendar date; toISOString() is
  UTC and dated a receipt booked after midnight CEST to the previous day.
- listExpensePayoutsDue pages through every registered claim with
  fetchAllRows instead of stopping at 500 rows: a person omitted or a
  total understated there is money the company owes someone.
- The attention resource's payout instruction names the liability
  account per row (2893 / 2018 / 2820) instead of only 2893/2820.
