Optimize PushServerUpdateJob performance with batch updates and async jobs

- Eager load service applications and databases to eliminate N+1 queries
- Replace individual model updates with batch database updates for applications, previews, and services
- Move connectProxyToNetworks to async ConnectProxyToNetworksJob to avoid blocking status updates
- Optimize Server.databases() and applications() methods with efficient database queries
- Use flatMap for cleaner collection transformations
