Add currency support and config management enhancements

This commit introduces significant updates to the application, focusing on currency support and improved configuration management. Key changes include:

- Added a `config_reset` flag in `update_metrics_job` in `App.py` to manage configuration resets.
- Modified `update_config` to handle currency changes and update notifications accordingly.
- Updated `MiningDashboardService` to fetch and include exchange rates and configured currency in metrics.
- Introduced utility functions for currency formatting and symbol retrieval in `notification_service.py`.
- Enhanced UI components in `main.js` and `boot.html` to support currency selection and display.
- Adjusted Docker Compose file to remove hardcoded wallet and power settings for better flexibility.

These changes enhance usability by allowing users to view financial data in their preferred currency and manage configurations more effectively.
