refactor(app): split MainWindowViewModel into partial files by area

1300-line monolith → 7 focused files (max 359 lines each):
  MainWindowViewModel.cs         core fields, constructor, lifecycle
  MainWindowViewModel.Wizard.cs  setup wizard and wallet open/close flows
  MainWindowViewModel.Settings.cs language, unit, overlay flags
  MainWindowViewModel.Sync.cs    server config, connection, sync loop
  MainWindowViewModel.Send.cs    send panel
  MainWindowViewModel.Contacts.cs contact management
  MainWindowViewModel.Receive.cs balance display, QR, addresses, tx details

No behaviour change, no XAML change, 127/127 tests pass.
