DS Epic: Balance Overview

### **Description**

A Balance Overview component displays a summary of a user's total asset holdings, including individual token balances and their equivalent values. It provides a clear and concise snapshot of the user's financial status within the DeFi ecosystem, aiding in quick assessment and decision-making.

The issue does not mention any files, tests, or entry points. Start by reviewing the design-system repository and existing component conventions, then clarify the required balance data, token values, equivalent-value display, and completion criteria before implementation.
