Fix restart initiated duplicate and restore activity logs

- Add restartInitiated flag to prevent duplicate "Proxy restart initiated" messages
- Restore ProxyStatusChangedUI dispatch with activityId in RestartProxyJob
- This allows the UI to open the activity monitor and show logs during restart
- Simplified restart message (removed redundant "Monitor progress" text)
