Bug Description

The application stores reviewCount in the Product document while individual reviews are stored separately in the Reviews collection.

Currently, there is no guarantee that the stored reviewCount value always matches the actual number of reviews associated with a product. As reviews are added, updated, deleted, migrated, or modified, the count can become stale and diverge from the real review total.
"""""""""""""""""""""""""""""""""
It is a critical issue because
""""""""""""""""""""""""""""""""""""
Review count is a key trust signal for customers.
Incorrect counts can mislead users about product popularity and credibility.
Analytics, sorting, filtering, and recommendation systems may rely on inaccurate data.
The issue can propagate across product cards, collection pages, search results, and product detail pages.

Steps to Reproduce

Navigate to collections page
Check review count on cards

Expected Behavior

Review count should always match the actual number of reviews associated with a product.
The application should maintain consistency between Product and Review data.
