Add support for Singlesig, Multisig, and Taproot with Keystone wallet.

• In the app, many hardware devices provide options for:

✅ Singlesig

✅ Multisig

✅ Taproot

However, the Keystone device does not show any such options while adding or importing the wallet. This makes it less flexible for users who want to use Keystone with various script types.
