davotoula 24a8540ad9 fix(nwc): never let a NIP-47 refusal or timeout reach the user as silence
Field report (BrollyZapper, 2026-08-25): a QUOTA_EXCEEDED on pay_invoice and a
RESTRICTED on list_transactions both reached the phone and showed nothing at
all — no toast, no dialog, no error state. The action simply looked like it had
not happened. Three separate defects produce that symptom.

1. The zap path had no user-visible timeout. NwcSignerState's 60s safety net
   only dropped the relay subscription: it never cleaned the tracker entry and
   never told anyone. A response lost in transit (the same trip measured
   relay.damus.io refusing 40% of websocket upgrades) was therefore permanent
   silence. The timeout now retires the request and fires an onTimeout callback
   that every interactive caller renders. NwcPaymentTracker.cleanup returns
   whether it was the one to remove the entry, so a timeout racing a real
   response stays quiet rather than overwriting the wallet's own answer.

2. WalletTransactionsScreen never read walletViewModel.error. The ViewModel set
   it correctly on both the refusal and the timeout paths; the view branched on
   isLoading/isEmpty only and rendered "No transactions yet" over the top of it.

3. Consumers matched on PayInvoiceErrorResponse, which the deserializer only
   produces when result_type == "pay_invoice". NIP-47 does not require a wallet
   to echo result_type on an error, and an error for any other method takes the
   generic NwcErrorResponse branch — so those refusals were dropped without a
   word, and the DVM screen went as far as thanking the user for a payment that
   had just been refused. All of them now match IErrorResponseLike, and the
   remaining else branches report an unreadable response instead of nothing.

Also: errorMessage() falls back to the code name when a wallet sends `code`
without `message` (message is optional in NIP-47), and stale wallet errors are
cleared when a transaction fetch or page load succeeds.
