Refactor CurrencyController to enhance rate fetching and introduce new methods

- Replaced the `getCurrentRates` method with `runAllFetchs` to dispatch fetching jobs for currency and gold rates synchronously.
- Added `getAllRates`, `getGoldRates`, and `getGoldRateByName` methods to improve data retrieval from respective JSON files.
- Updated error messages for clarity and consistency.
- Streamlined JSON file handling by using variables for file paths, enhancing maintainability.

These changes improve the CurrencyController's functionality and organization, facilitating better management of financial data.
