Add domain layer for Product microservice:
- BaseEntity with audit fields (Id, CreatedBy, UpdatedBy, timestamps)
- Product entity (drops OrderDetails nav property from monolith)
- ProductCategory entity with Products collection
- ProductDto matching monolith ProductVM shape
- CategoryDto for category projections
- Remove .gitkeep placeholders from Entities/ and Interfaces/
