DevPortalModal
fun DevPortalModal(title: String, onDismiss: () -> Unit, onOpenWireframeList: () -> Unit, stateControls: @Composable () -> Unit? = null)
Bottom-sheet modal opened by the dev FAB on any screen.
Always shows the "View all wireframes" button at the bottom. Takes an optional stateControls slot that hosts per-screen controls (state toggles, option checkboxes). Pass null for screens without swappable states (e.g., the real app).
