feat(app): multi-wallet chooser, confirm-password, encrypt toggle

Browse Source 
Multi-wallet (§8):
- AppPaths.WalletFiles(net) enumerates all *.wallet.json in the wallets
  dir; WizardStartOpen shows a chooser step when more than one is found
- New StepChooseWallet + ChooseWalletCommand; Back from StepOpen returns
  to chooser (or to StepStart when only one wallet)
- WalletFileEntry record for the chooser ItemsControl

Password step (Electrum style):
- ConfirmPasswordInput: password must be typed twice before creating
- EncryptWallet checkbox (default true); when unchecked, password is
  null (plaintext file) with an explicit warning
- Validation: empty password with encryption on → msg.password.required;
  mismatch → msg.password.mismatch
- ConfirmPasswordInput cleared on wallet open and wizard back

AppPaths:
- DefaultDataRoot() is now platform-aware: %APPDATA%\PalladiumWallet on
  Windows, ~/.palladium-wallet on Linux/macOS (matches §8 convention)
- Legacy root fallback removed (no prior releases to migrate from)

i18n: wiz.choose.title, wiz.password.confirm, wiz.password.encrypt,
wiz.password.encrypt.hint, msg.choose.wallet, msg.password.required,
msg.password.mismatch — all 6 languages
