fix(realtime): sync instance/workspace list state without manual refresh

- Invalidate workspace list cache after assigning servers/users so
  server/user counts on workspace cards update immediately.
- Invalidate node/VM caches after workspace server/user assignment so
  the Nodes page reflects visibility changes right away.
- Soft-delete the cached VM/LXC row and broadcast vm_deleted the moment
  a VM/container is destroyed, instead of waiting for the 10s
  background sync_vm_cache tick.
- Invalidate the VM list on the frontend when a deploy task completes,
  since the backend already persists the new instance to cache
  synchronously before marking the task done.
