This update removes style settings that were defined but not actually used across several Odoo Enterprise areas. It helps keep the codebase cleaner and easier to maintain, with no expected change to how users see or use the product.

This commit removes assigned but never used SCSS variables.

Argentine electronic invoicing and VAT reporting now use the shared invoice currency rate stored on accounting entries. This keeps enterprise localization aligned with the main accounting changes and helps ensure consistent currency conversion data across reports and documents.

*: l10n_ar_edi,l10n_ar_reports

In the related community PR the field 'l10n_ar_currency_rate' was removed in favor of the new stored 'currency_rate' field on account.move .
This commit does the necessary changes in enterprise.
