fix(desktop): use Electron's native Notification (reliable click-to-open)

node-notifier/SnoreToast click callback never fired without the crashing wait mode. Switch the
chat toast to Electron's built-in Notification: shows avatar + message and its 'click' event
reliably raises the app + opens the chat. No SnoreToast, no external tools.
