Replaces the custom settings directory with a .env file for configuration. Updates backup and restore logic to handle .env instead of settings, and sets required Django environment variables explicitly. Simplifies installation and update scripts for better maintainability and security.
Replaces 'uv sync --no-dev' and editable pip install with 'uv venv' and standard pip install in both wger.sh and wger-install.sh. This streamlines the installation and update process for wger.
