Refactor the currency management system to eliminate the redundant
`rate_to_aed` field and transition to a single-base model where all
rates are stored relative to the Iranian Rial (IRR).
Key changes:
- Removed `rate_to_aed` from `currencies` table via new migration.
- Updated `ExchangeRateService` to handle rates using a single
`currency_code` parameter instead of currency pairs.
- Refactored `UpdateExchangeRates` command to fetch rates from the
Exir.io API and support multiple currencies (AED, USD, EUR, CNY).
- Updated Filament resources (`CurrencyResource`,
`ExchangeRateHistoryResource`) and widgets to reflect the new
single-base architecture.
- Improved `PriceCalculatorService` to use the updated service
methodology for fetching the AED/IRR conversion rate.
- Localized console command output to Persian.
Refactor the Filament dashboard by replacing the legacy FinanceOverviewWidget
with a new set of specialized widgets:
- DashboardInfoWidget for general information
- ExchangeRateWidget for real-time rate monitoring
- WalletStats for financial overview
Additionally, refactor the ExchangeRateService to improve encapsulation
and clean up the ExchangeRateHistory model by moving business logic
(change calculation and recording) from the model to the service layer.
Changes include:
- Removing deprecated helper methods from ExchangeRateHistory model
- Implementing direct queries in ExchangeRateService to replace model scopes
- Adding support for rate chart data retrieval
- Reordering and updating widget sorting in AdminPanelProvider
Introduce a mechanism to track and audit changes in exchange rates.
This includes:
- Creating `ExchangeRateHistory` model and migration to store rate changes.
- Implementing `ExchangeRateService` to encapsulate rate logic.
- Updating `UpdateExchangeRates` command to record history when rates change.
- Adding `ExchangeRateHistoryResource` to the Filament admin panel for monitoring.
