Systant is designed as a userspace controller rather than a system
daemon, so it makes more sense to run as a user service with access
to the user's environment, PATH, and session (for audio control, etc).
Changes:
- Remove user/group options (runs as current user)
- Use systemd.user.services instead of systemd.services
- Remove hardening options (not needed and would restrict access)
- Add package to environment.systemPackages
Enable with: systemctl --user enable --now systant
