chore: merge from develop to preview

[jorbuedo]

Note

Use signed transaction bytes directly for submission, remove NIGHT redemption operation detection, and always pass CBOR to the review screen without dev gating.

• Transaction signing/submission:
  • useOnConfirm.signTx: now returns signedTxBytes alongside signedTx and txId; txId computed from signed bytes.
  • useOnConfirm.submitTx: submits using signedTxBytes directly (avoids re-serialization via Transaction.toBytes()), converts to base64 for API.
• Review screen:
  • ReviewTxScreen: remove useAuth and dev gating; always pass params.cbor to ReviewTx; minor import consolidation.
• Operation classification/display:
  • getOperationTypeKey and operationDisplay: comment out NIGHT redemption detection logic; retain swap/smart contract checks.
