Make proxy restart run as background job to prevent localhost lockout

When restarting the proxy on localhost (where Coolify is running), the UI becomes inaccessible because the connection is lost. This change makes all proxy restarts run as background jobs with WebSocket notifications, allowing the operation to complete even after connection loss.

Changes:
- Enhanced ProxyStatusChangedUI event to carry activityId for log monitoring
- Updated RestartProxyJob to dispatch status events and track activity
- Simplified Navbar restart() to always dispatch job for all servers
- Enhanced showNotification() to handle activity monitoring and new statuses
- Added comprehensive unit and feature tests

Benefits:
- Prevents localhost lockout during proxy restarts
- Consistent behavior across all server types
- Non-blocking UI with real-time progress updates
- Automatic activity log monitoring
- Proper error handling and recovery
