Subject: [PATCH] perf: optimize MediaPickerModal by using useMemo for derived
library data
Refactor MediaPickerModal to derive its image library using useMemo from products, collections, and settings props. This eliminates the extra render cycles previously caused by local data fetching and state updates (useEffect + setIsLoading + setLibrary).
The refactor also includes:
- Memoization of normalized image URLs to avoid repeated calls to the potentially slow normalizeImageUrl utility.
- Removal of redundant internal state variables (library, isLoading, error).
- Simplification of the component's useEffect hook.
- Lazy loading for images in the media grid to further enhance performance.
This change follows React performance best practices by treating the media library as derived data rather than a separate state, leading to a more efficient and predictable rendering cycle.
