Fix post-purchase state for buy-now edition listings

[Copilot]

Buy-now purchases on edition listing pages were confirming without any clear success state, then leaving the page in a stale intermediate state. The result was an incorrect remaining-count display until a hard refresh, even though the purchase had succeeded.

• Post-purchase flow

  • Keep the buyer on the listing page after purchase confirmation instead of immediately redirecting away.
  • Show an inline success message on the listing page once the transaction confirms.

• Edition supply accounting

  • Correct the optimistic totalSold update for ERC1155 listings by applying purchaseQuantity * totalPerSale, so the remaining count matches the on-chain purchase semantics.
  • Mark the listing finalized only when the recomputed remaining supply reaches zero.

• Duplicate confirmation handling

  • Gate purchase side effects by purchaseHash so the confirmation effect only runs once per transaction.
  • Avoid repeated optimistic increments and repeated post-confirmation refresh behavior.

• Buyer list synchronization

  • Restore optimistic buyer-list updates on listing pages by always registering the buyer-added handler.
  • Keep the buyers list in sync with the confirmed purchase before the background refetch catches up.

const totalPerSale = parseInt(prev.totalPerSale || "1");
const copiesPurchased = purchaseQuantity * totalPerSale;
const newTotalSold = currentTotalSold + copiesPurchased;
