Overview

Abstract base class for all database view models.

This class provides:

1. Read replica routing - queries go to replica in production/staging
2. Write protection - prevents accidental INSERT/UPDATE/DELETE
3. Consistent behavior for all view models

Usage:
class ViewProductCatalog < ApplicationViewRecord
# ...
end

All 74 view models inherit from this class to ensure consistent
read replica routing and write protection.
