Reconcile vtxos against the server before a headless NWC payment

The sync merge is additive by design, so a vtxo spent on one device can
survive in another device's state looking spendable. The interactive
send path reconciles on intent; the NWC path connected and spent blind,
so a wallet answering from stale state picked an already-spent coin and
the ASP refused with 'vtxo … is not spendable (state: spent)'.
