feat(ui): wizard flows for xpub/xprv and WIF import

Browse Source 
Add two new import paths to the setup wizard:

- "Importa xpub / xprv": accepts any SLIP-132 key (xpub/ypub/zpub or
  xprv/yprv/zprv), auto-detects script type from the version prefix,
  and saves a watch-only or fully-spendable HD account accordingly.

- "Importa chiave WIF": accepts one or more WIF private keys (one per
  line), goes through script-type selection, and saves an ImportedKeyAccount.

WizardFlowKind enum (New, Restore, ImportXkey, ImportWif) governs which
steps are shown; WizardBack() updated for all four flows. OpenLoaded()
updated to accept IWalletAccount and display wallet kind tags
(watch-only / imported) in the network info line.

Localization keys added for all six languages (it/en/es/fr/pt/de).
ViewModel._account changed from HdAccount? to IWalletAccount?.
