InstrumentPickerPage
StockSharp.Broker.Maui.Backoffice.Pages
Modal instrument picker. Hosts InstrumentPickerViewModel and pops itself once the VM's SelectedResult task resolves — either through a row tap (positive result) or the Close button (null).

方法
AwaitSelectionAsync() : Task<TradingInstrument>
Convenience helper for the caller (TenantSettingsPage): pushes this picker modally and returns the selection, or null when the operator dismissed it. The caller does not need to remember the VM's TaskCompletionSource pattern.
