/// Purpose: Disconnect tab — privileged-helper toggle and explanatory caption.
///          Extracted from PreferencesView to keep every tab file under 500 lines.
/// Inputs:  @AppStorage binding for the feature-enabled flag; injected closure that
///          tells the coordinator to register/unregister the SMAppService daemon.
/// Outputs: writes to UserDefaults; calls enableDisconnectHelper when the toggle changes.
/// Constraints: @MainActor (SwiftUI). The helper is off by default; enabling it triggers
///          a one-time admin authorization prompt via SMAppService.
/// SPORT: MASTER-PREFS
