Replace the direct private-key display in the address detail overlay with a
two-step reveal flow:
- Unencrypted wallet: clicking Show reveals the WIF key immediately.
- Encrypted wallet: clicking Show opens a modal password-prompt overlay; the
key is displayed only if the entered password matches the wallet file
password; a wrong password shows an inline error without closing the prompt.
Hiding the key (Hide button) clears the revealed state. Closing the address
overlay or opening a different one always resets both the reveal state and
the password prompt, so no sensitive material lingers between sessions.
Translate every Italian /// XML doc comment, <!-- --> XAML comment, and
// inline comment to English across all source files (Core, App, tests).
Add the language policy to CLAUDE.md (conversation Italian; all code
and docs English). Update one test assertion that checked an Italian
exception message that was also translated.
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?.
