SPV is the only verification method the wallet uses, so showing it as a badge adds no information — if a transaction appears confirmed, it has already passed Merkle verification. - Remove the SPV chip from the transaction detail overlay - Remove the Verificata column from the history list (desktop and mobile) - Drop VerifiedText property from TransactionDetailsViewModel - Drop the Verificata field from HistoryRow - Remove the orphaned tx.verified loc key
