Refactor metrics handling and remove scheduler

- Removed the metrics scheduler functionality from the bot, transitioning to real-time metrics updates via middleware.
- Enhanced logging for metrics operations across various handlers to improve monitoring and debugging capabilities.
- Integrated metrics tracking for user activities and database errors, providing better insights into bot performance.
- Cleaned up code by removing obsolete comments and unused imports, improving overall readability and maintainability.
