/**
 * Subclass of [ImageViewerDialogFragment] used by Galeria.
 *
 * Two responsibilities:
 *   1. When [isAppearanceLightSystemBars] is non-null, present an edge-to-edge
 *      dialog with the system bars colored to match the light/dark theme.
 *      When null, fall through to the library's default dialog.
 *   2. Forward the dialog's onDismiss to [onDismissCallback], so the JS side
 *      can be notified when the viewer is dismissed (any dismissal mechanism:
 *      swipe-to-dismiss, system back button, programmatic dismiss).
