- Added the `FetchGoldRates` job to retrieve gold rates and the `MergeCurrencyAndGoldRates` job to combine currency and gold rates.
- Updated the `getCurrentRates` method to read from a new JSON file `merged/rates.json` instead of the previous `currency/today.json`.
- Commented out the synchronous dispatch of the fetching jobs for future implementation.
This commit enhances the CurrencyController's functionality by preparing it for integrated financial data management.
Implemented a new method `getCurrencyRateByName` in the CurrencyController to fetch the currency rate based on the provided currency name from a JSON file. The method handles cases where the file does not exist or the currency is not found, returning appropriate JSON responses for each scenario.
