- Configure ProductDbContext with DbSets for Product and ProductCategory
- Port ORM configuration verbatim from monolith:
  - AppProducts table: Name indexed/required/100, Description/500, Icon unicode(false)/256,
    self-referencing Parent→Children with Restrict, BuyingPrice/SellingPrice decimal(18,2)
  - AppProductCategories table: Name required/100, Description/500
- Add EnsureCreated() on startup for automatic schema creation
- Verified build succeeds and tables are created correctly in PostgreSQL
