fix(desktop): pass enabled/path/args/name to setLoginItemSettings per platform

macOS: add args:[--hidden] alongside openAsHidden for defence-in-depth detection on macOS 13+.
Windows: add enabled/path/args/name so re-enabling the toggle clears the StartupApproved\Run disable marker.
Linux: add deterministic name:'backspace' so the .desktop filename is stable across Electron/AppImage updates.
