Keep guests running during the PVE 8 to 9 upgrade and complete the help menu

- The upgrade no longer restarts pve-manager while preparing the host, so running guests are not stopped
- The upgrade stops before touching any repository when the Proxmox VE 8 update fails or is cancelled
- The unattended mode continues into the upgrade instead of exiting after the mode question
- Without a subscription, the enterprise repository added by pve-manager 9 is left disabled after the upgrade
- grub-efi-amd64 is installed with its output visible in interactive mode
- Help menu: qm unlock and pct unlock entries in the VM/CT section, renumbered items and aligned labels
- Help menu: pvesm scan nfs takes the server address, and pveupgrade is described as the interactive upgrade
- Help menu: an empty choice no longer runs the previous command
- translate() finds catalog entries for texts with leading or trailing spaces and keeps the padding
- Spanish help menu texts use the tú form and the Intro key
- New help and upgrade messages translated into all languages
