feat: Add SysV init support for legacy systems. Related to #894
Adds support for systems that use SysV init (like Asustor NAS) that don't have systemd, OpenRC, or launchd. The installer now: - Detects /etc/init.d as a fallback when no other init system is found - Creates an LSB-compliant init script with start/stop/restart/status - Uses update-rc.d (Debian) or chkconfig (RHEL) to enable on boot - Falls back to manual rc.d symlink creation if neither tool is available - Properly cleans up on uninstall
