feat: add limit order support with AI context awareness

- Add OpenOrderInfo struct and OpenOrders field to trading context
- Support new AI actions: place_buy_limit, place_sell_limit, cancel_order, cancel_all_orders
- Include existing open orders in AI prompt to avoid duplicate orders
- Add open orders display table in trader dashboard
- Fix Hyperliquid symbol conversion and order status parsing
- Add i18n translations for open orders
