Describe the Bug

The Gallery component in the e-commerce template uses 'searchParams.values().toArray()' which is not a standard JavaScript method. This causes a runtime TypeError when users click on product detail pages.

Error message:
TypeError: searchParams.values().toArray is not a function. (In 'searchParams.values().toArray()', 'searchParams.values().toArray' is undefined)

Location: src/components/product/Gallery.tsx:29

Current problematic code:
const values = searchParams.values().toArray()

Proposed fix:
const values = Array.from(searchParams.values())
The .toArray() method on iterators is not yet standardized in JavaScript. The standard approach is Array.from() or spread operator [...iterator].
