Integrate User-Provided Image URLs into Token Cards & Details Pages

[iShinzoo]

Description

When users create a token, they input an image URL. This URL Image should be displayed:

• On the homepage token cards (thumbnail)
• On the token details page (full-size image)

Acceptance Criteria

• Fetch and display the image URL from the token’s metadata in the frontend.
• Add image rendering to Home.tsx (homepage) and token-detail/address.tsx.
• Implement error handling for broken URLs (e.g., fallback placeholder image).
• Ensure images are optimized (lazy-loading, CDN caching).
