Always render VM list; surface SPICE connect target for diagnosis

- Auto-connect (single-VM shortcut and autostart match) now renders the
  VM list first instead of skipping straight to the connect attempt.
  With cluster dedup collapsing 3 duplicate entries down to 1, the VM
  vanished from the screen entirely whenever the connection failed.
- proxmox:connect now returns the resolved host:port it handed to
  remote-viewer, shown in the success notice, so connection failures
  (e.g. Proxmox handing out a cluster-internal node address the client
  cannot route to) can be diagnosed without racing delete-this-file.
