VIES answers HTTP 200 even when it couldn't actually perform the check
(actionSucceed: false, e.g. MS_UNAVAILABLE — Germany's own national
gateway does this fairly regularly). checkVatIdViaVies() only ever read
data.valid, which is absent on that response shape, so it silently
read as valid: false — a real, currently-registered German VAT ID
(reported: DE351362947) looked rejected. Worse, /api/checkout/validate-
vat then wrapped even a correctly-returned ok:false as { ok: true,
valid: false }, which the client reads as "invalid" rather than
"unavailable" — the actual bug the user hit, compounding the vies.ts
gap. Both are fixed now: an unconfirmable check surfaces to the client
as ok:false, which CheckoutContent.tsx's handleVatIdBlur already
correctly renders as "USt-IdNr.-Prüfung derzeit nicht möglich"
instead of a rejection. Same fix applied to the payload backend's own
copy of vies.ts (company-settings' VAT check).
