Enhance the "Grid Levels" Tab to Show Unmatched/Single Orders

In the current "Grid Levels" tab, the interface primarily highlights completed buy-and-sell pairs (matched trades). However, from a risk management perspective, it is critical to see the full picture. Please update this tab to list all active, open, or partially filled single orders—such as a buy order that has been executed but whose corresponding sell order is still waiting, or vice versa. Listing both matched pairs and unmatched single orders chronologically or by price levels will give traders ultimate clarity on their current exposure.
