PBS datastores are now displayed in the Storage overview alongside PVE
storage. Each PBS datastore is converted to a Storage entry with:
- type: 'pbs'
- content: 'backup'
- shared: true
- active: based on PBS instance status
This provides a complete picture of all storage resources in one view
while keeping detailed PBS info in the dedicated PBS section.
