feat: implement dynamic currency handling

The updates include:

- Added `quiqqer/currency` package to `composer.json`.
- Refactored code in `Basket.php`, `OrderProcess.php` and `Utils.php` to use the new
`getRuntimeCurrency` function for currency handling.
- Removed hardcoded currency setting in `Basket.php`.
- Updated code in `OrderProcess/Basket.php` to correctly reference new Basket class.
- Added logic to set currency from product data in `Utils.php`.

These changes allow for dynamic handling of currencies across the application, reducing the need
for hardcoded values and enhancing flexibility and maintainability.
