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.
