Replace duplicated switch/case blocks across 4 methods with a clean abstract driver pattern: - ExchangeRateDriver (abstract): defines getExchangeRate(), getSupportedCurrencies(), validateConnection() - CurrencyFreakDriver, CurrencyLayerDriver, OpenExchangeRateDriver, CurrencyConverterDriver: concrete implementations - ExchangeRateDriverFactory: resolves driver name to class, with register() method for module extensibility Delete ExchangeRateProvidersTrait — all logic now lives in driver classes and ExchangeRateProviderService. Adding a new exchange rate provider only requires implementing ExchangeRateDriver and calling ExchangeRateDriverFactory::register() in a module service provider.
