Add products and sales management modules with database schema and validation
- Introduced `ProductsModule` to manage product data, including read and write controllers. - Created database migrations for the `products`, `sales_requests`, `sales_orders`, `sales_invoices`, and related tables, including constraints and unique indexes. - Implemented validation for product fields such as code, name, unit, and brand with corresponding utility functions. - Developed service and repository layers for handling product and sales data operations. - Added unit tests for the products and sales services, repositories, and controllers to ensure functionality and correctness. - Updated application module to include the new `ProductsModule` and related sales modules for better organization.
