[UI] Design the "Interactive Function Card"

Title: [UI] Design the "Interactive Function Card" for the Sandbox

📝 Description

Each function in the smart contract needs a "Card" where users can see parameters and click "Execute." This is the heart of the "Swagger for Web3" experience.

🎯 Goal

Create a React component in libs/sandbox that renders a function's name, its inputs as text fields, and a "Run" button.

✅ Requirements

• Inputs must dynamically generate based on the function's arguments.
• Include a "Result" area that displays the output of the contract call (or an error message).
• Styled to look professional and developer-centric.
