// PendingOrdersPanel — queued-order approval popover (replaces the standalone
// Action Center dock tab). Renders the orders queued by ActionCenter from the
// headless paths (AI/workflow/broadcast/basket) and lets the user Approve /
// Reject them (per-row and in bulk). Shown as a frameless Qt::Popup anchored to
// the status-bar PendingOrdersBadge.
//
// The per-account Auto ↔ Semi-Auto mode toggle now lives in Account Management,
// not here. This is a pure view (P6): it reads from and calls ActionCenter;
// it never spawns Python, makes HTTP calls, or owns business logic.
//
// Live updates: subscribes to ActionCenter signals (pending_order_created,
// order_approved, order_rejected, stats_updated) in the constructor and
// refreshes without polling (D3).
