Add standalone Python entrypoint for EasyHAProxy and pip-based installation

- Introduced `/scripts/.venv/bin/easy-haproxy` as the default entrypoint for standalone environments.
- Added `_build_parser` and `start` functions to enable CLI-driven functionality configuration.
- Updated packaging to reflect new `easyhaproxy.main` module and adapted project name from `easymapping` to `easyhaproxy`.
- Modified `Dockerfile` to align with new script paths and entrypoints for better portability.
- Enhanced documentation with dedicated sections for pip-based installation, CLI references, and systemd setup for non-Docker environments.
- Adjusted helm, plugin, and environment-related docs for accurate sidebar ordering.
- Added a new GitHub workflow to automate package publishing to PyPI.
