Add currency test data and enhance FetchCurrencyRates job with TCMB integration

- Introduced a new JSON file containing currency rates for various currencies, including USD, EUR, and GBP, to standardize currency data representation.
- Enhanced the FetchCurrencyRates job to fetch USD data from TCMB if not available, improving data reliability.
- Added logging for TCMB data fetching process to assist in monitoring and debugging.

These changes collectively improve the accuracy and robustness of currency rate handling in the Truncgil Finance application.
