Add RunAllFetchs command to execute currency and gold rate fetching jobs sequentially

- Introduced a new console command `RunAllFetchs` to streamline the execution of `FetchCurrencyRates`, `FetchGoldRates`, and `MergeCurrencyAndGoldRates` jobs.
- Implemented synchronous dispatching of jobs with timing results displayed in a table format for performance monitoring.
- This command enhances the application's ability to fetch and merge financial data efficiently in a single execution step.
