refactor(orders): replace local state machine with minimal cache

Strip store/orders.ts to a thin local cache with setOrders and
updateOrder only. Remove all client-side state transition logic,
actor validation, chat sync, notification generation, and wallet
integration — these are now handled by the backend API.

Fix components/order-actions.tsx and stores that depended on
the removed order store methods (markDisputed, autoTimeout*).
