AITCORE-4: Update price format in component

* Fix issue: Deprecated Functionality: NumberFormatter::setAttribute(): Passing null to parameter #2 ($value) of type int|float is deprecated in /var/www/html/vendor/magento/module-directory/Model/Currency.php on line 497
* Rearrange imports
* Add `@throws` to method annotation
* Fix is safe because the method's default `$precision` [appeared in Magento 2.0.0](https://github.com/magento/magento2/blame/0f9a056c8d83c4f319626b3e56ec52a533999f25/lib/internal/Magento/Framework/Pricing/PriceCurrencyInterface.php#L53)
