Data not updating properly with server folder

### Nova version

v2.0.1

### Observed behavior

When I click on one folder and then switch to another, the server name updates correctly, but the status (ON/OFF), RAM, disk, and CPU monitoring information still shows data from the previous server. In short, the information doesn’t refresh properly when changing folders.

### Expected behavior

When switching between folders, all displayed information (server name, status, RAM, disk, CPU, and network metrics) should update to match the selected server, without showing data from the previously opened folder.

### Steps to reproduce

1. Open the dashboard. with multiple folder and server into
2. Click on a first folder containing several servers.
3. Select a server and observe its status, RAM, disk, and CPU information.
4. Click on another folder to view a different server.
5. Notice that while the server name updates, the monitoring information (status, RAM, disk, CPU) still shows data from the previous folder.

### Is there an existing issue for this?

- [x] I have searched the existing issues

Start by tracing the dashboard state used when switching between folders and servers. Reproduce the issue with two folders, then verify that server status, RAM, disk, CPU, and network metrics all refresh for the newly selected server instead of retaining the previous server's data.
