Refactor configuration and scripts for Archipelago backend and ISO build

- Updated Cargo.toml to remove unnecessary package backtrace optimizations.
- Changed default bind host and port in config.rs for broader accessibility.
- Renamed state_manager to _state_manager in server.rs for clarity.
- Updated user field to _user in PodmanClient and DockerRuntime for consistency.
- Modified build-debian-iso.sh to enhance welcome message and backend startup instructions.
- Improved archipelago-menu.sh to display backend status and updated Web UI URL.
- Enhanced install-to-disk.sh for better package management and user creation during installation.
