Enhance MarketDashboard to filter orders by current user

- Introduce computed properties to count orders based on the current user's public key.
- Update orderCount to reflect only the user's orders as a buyer.
- Update pendingOrders to count only the user's pending orders as a seller.
- Improve user experience by providing personalized order statistics.

These changes ensure that users can easily track their own orders and pending transactions within the MarketDashboard.
