Migrate exchange rate handling from static system settings to a
centralized `ExchangeRateService`. This change ensures that currency
rates are managed through a single source of truth that supports
history tracking, approval workflows, and API updates.
Laravel:
- Remove manual exchange rate fields (`aed_to_irr`, `usd_to_irr`, etc.)
from `IfnexSettingsPage` and the `SystemSetting` persistence logic.
- Update `PricingPageController` and `PriceCalculatorService` to
retrieve live rates from `ExchangeRateService` instead of `SystemSetting`.
- Refactor `IfnexSettingsPage` UI to display current rates as
read-only information with a link to the dedicated exchange rate
management resource.
Documentation:
- Update `CLIENT_DELIVERY.md` to reflect the change in exchange rate
management workflow.
Improve the reliability and usability of the shipping rates import
process and update PDF document templates for better visual fidelity.
- Enhance `ImportShippingRates` command with `--clear` and `--dry-run`
options to prevent accidental data loss and allow safe testing.
- Implement error handling and statistics tracking in `ShippingRatesImport`
to capture skipped rows and import errors.
- Refactor AWB and Label PDF templates to use A4 standard dimensions
and improved CSS layouts.
- Integrate company logo into PDF headers.
- Add a new pricing inquiry page and navigation link.
- Clean up obsolete test scripts.
