This pull request introduces significant refactoring and enhancements to the product and discount use cases, focusing on simplifying currency management, improving stock calculation, and enhancing product lifecycle operations. Key changes include removing currency-specific price handling, introducing stock recalculation logic, and refining discount application methods.

Product Use Case Changes:

Currency Management Simplification:

• Removed CurrencyPriceInput and all related logic for handling currency-specific prices in CreateProductInput, CreateVariantInput, UpdateVariantInput, and AddVariantInput. Products and variants now use a single currency specified during creation.

• Updated logic to persist recalculated stock in the repository after variant operations. ([internal/application/usecase/product_usecase.goL479-R367](https://github.com/Zenfulcode/CommercifyGO/pull/37/files#diff-c590c807754d06047fffec1aba0a62b2b7a9a4addfa29b6261f94bda1cf51777L479-R367))

Lifecycle Improvements:

• Added an Active flag to CreateProductInput and UpdateProductInput to manage product activation status. Removed default variant creation logic and simplified variant handling.
