Added parent-child relationship to categories, allowing organization
of categories into submenus (e.g., Apparel > Adults, Kids, Babies).
Changes:
- Add parentId field to Category model
- Create foreign key relationship for category hierarchy
- Update homepage to query only top-level categories (parentId = null)
- Include children categories for future use in category menus
Database migration:
- Adds parentId column to Category table
- Sets up CASCADE delete to remove children when parent is deleted
This enables menu structure like:
Apparel
- Adults
- Kids
- Babies
Drinkware
Phone Cases
etc.
