- PeerFiles: new confirmation step after "pay from ecash" — shows the amount and
which wallet will be spent (Cashu/Fedimint) with balances, lets the user switch
backends, and a styled Confirm button. The chosen backend is passed to the
payment so it spends exactly what was confirmed.
- content.download-peer-paid: accept `method` (cashu|fedimint) to honor the
confirmed choice; log the backend + outcome; backend-specific rejection errors
("not in the same Fedimint federation" / "doesn't accept your Cashu mint").
- AUTO-REFUND: a minted token whose sale fails (peer unreachable, rejected, or
error) is now reclaimed (fedimint reissue / cashu receive) so the buyer no
longer loses the spent ecash — fixes the stuck-Fedimint-notes report.
- wallet.ecash-balance already reports cashu_sats/fedimint_sats/total_sats which
the confirm screen uses to pick/show the covering wallet.
