* Revert "server: refactor listNetworks api database retrievals (#9184)"

This reverts commit c7f1ba5.

* Fix snapshot chain being deleted on XenServer (#9447)

Using XenServer as the hypervisor, when deleting a snapshot that has a parent, that parent will also get erased on storage, causing data loss. This behavior was introduced with #7873, where the list of snapshot states that can be deleted was changed to add BackedUp snapshots.

This PR changes the states list back to the original list, and swaps the while loop for a do while loop to account for the changes in #7873.

Fixes #9446

* UI: Display Firewall, LB and Port Forwading rules tab for CKS clusters deployed on isolated networks (#9458)
