Kazem Alghasi 58493feca4 refactor(currency): IRR as single base currency for all shipping rates ... Make Iranian Rial (IRR) the sole base currency for shipping rates: - RateImportService now converts all imported rates to IRR at import time using the current daily exchange rate (source currency AED/USD/ EUR/IRR). Rates are stored in rate_entries with currency='IRR'. - PriceCalculatorService looks up IRR rates directly — no conversion at calc time. Also fixes a pre-existing bug where extras (in IRR) were incorrectly added to the AED base before conversion. - RateEntry::lookup() default currency changed from 'AED' to 'IRR'. - Migration changes the column default to 'IRR'. - Filament import form: relabel 'Rate currency' to 'Source currency (in Excel file)' with helper text explaining the conversion. - WordPress JS: update price summary labels from 'درهم' to 'ریال' and drop the deprecated net_dirham field. Architectural benefit: rates are 'frozen' in IRR at import time — daily exchange rate changes only affect NEW imports, not already- stored rates. This is more stable and predictable for customers.		2026-10-29 17:01:30 +03:30
