Add auto-alert toggle and priceQuery

Replace conditional auto-alert row with a Toggle-backed view and add a priceQuery to support showing current price. Introduces autoAlertItemModel and isAutoAlertEnabledBinding in the view model, plus toggleAutoAlert(enabled:) to add/delete the default auto alert and handle permissions. Scene now binds priceQuery (instead of query), exposes a dedicated autoAlertToggleView, removes the empty-state overlay, and makes onDelete private. Tests updated to assert the new binding behavior.
