fix(expenses): review follow-ups from #2333 (#2352)

- The owner's claimant key is trimmed and lower-cased, the same rule the
  payout RPC applies, so "Jakob" and "jakob " are one person with one
  Att göra row and one exact-amount match.
- The inbox pages through every registered claim (fetchAllRows) before
  pairing, so a long backlog can never understate a person's debt.
- A foreign receipt's VAT field is locked at 0 and 0 is what is submitted.
- Transport failures in the one-click and picker confirms show the
  destructive toast instead of failing silently.
- The open-claims flag is set only after the stale-fetch guard, and a
  payout match decrements the inbox count like every other row exit.
- Test: reset the live-link mock before the bank_line junction case.
- Wording: "Återbetalning av utlägg".
