refactor(ui): remove SPV badge from tx detail and history

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
