Enhance Makefile and update metrics handling in bot

- Added new commands in the Makefile for restarting individual services: `restart-bot`, `restart-prometheus`, and `restart-grafana`.
- Updated Prometheus and Grafana dashboard expressions for better metrics aggregation.
- Removed the `main_with_metrics.py` file and integrated metrics handling directly into the main bot file.
- Refactored middleware to improve metrics tracking and error handling across message and callback processing.
- Optimized metrics recording with enhanced bucket configurations for better performance monitoring.
