Current trade UI improvements

We have made a few improvements to how open trades are displayed in the dashboard.

What changed

Updated Current Trade cards so the header now opens as a dropdown.

Added a smoother animated expand and collapse effect for trade details.

Improved the Dashboard page so it now shows all current open trades instead of only the latest trade.

Reused the Current Trade card layout on the Dashboard for a more consistent experience.

Live price tracking now supports multiple open positions on the Dashboard.

These changes make it easier to monitor active positions while keeping the Dashboard cleaner at a glance.
