fix(frontend): fix-productcard-fallbacksrc-v2

[ramya2006sri]

Description

Fixes an issue where ProductCard displays a broken image icon when the product image URL is invalid, deleted, or unavailable.

Changes Made

• Added fallbackSrc to the Chakra UI Image component in ProductCard.jsx
• Uses the same placeholder image pattern already used in ProductPage.jsx
• Prevents broken image icons from being shown to users

Before

• Broken image icon was displayed when the product image URL failed to load.

After

• A placeholder image is displayed when the product image cannot be loaded.

Testing

• Verified that the Image component includes a valid fallbackSrc
• Confirmed behavior is consistent with other components that already use image fallbacks

Fixes #384

Adds \allbackSrc\ to ProductCard Image — consistent with the existing pattern in ProductPage. Prevents broken image icons. The indentation/whitespace reformatting adds diff noise but the functional change is correct. LGTM.
