Refactor Docker and configuration files for improved structure and functionality

- Updated `.dockerignore` to include additional development and temporary files, enhancing build efficiency.
- Modified `.gitignore` to remove unnecessary entries and streamline ignored files.
- Enhanced `docker-compose.yml` with health checks, resource limits, and improved environment variable handling for better service management.
- Refactored `Dockerfile.bot` to utilize a multi-stage build for optimized image size and security.
- Improved `Makefile` with new commands for deployment, migration, and backup, along with enhanced help documentation.
- Updated `requirements.txt` to include new dependencies for environment variable management.
- Refactored metrics handling in the bot to ensure proper initialization and collection.
