Refactor project structure and enhance Docker support

- Removed unnecessary `__init__.py` and `Dockerfile` to streamline project organization.
- Updated `.dockerignore` and `.gitignore` to improve exclusion patterns for build artifacts and environment files.
- Enhanced `Makefile` with new commands for managing Docker containers and added help documentation.
- Introduced `pyproject.toml` for better project metadata management and dependency tracking.
- Updated `requirements.txt` to reflect changes in dependencies for metrics and monitoring.
- Refactored various handler files to improve code organization and maintainability.
