Use specific exit codes in PVE scripts

Replace generic exit 1 with distinct exit codes across tools/pve scripts to provide clearer failure signals for callers. post-pve-install.sh now returns 105 for unsupported Proxmox versions; pve-privilege-converter.sh uses 104 for non-root, 234 when no containers, and 235 for backup/conversion failures; update-apps.sh maps backup failures to 235, missing containers/selections to 234 (and UI cancellations to 0), missing backup storage to 119, and returns the actual container update exit code on failure. These changes improve diagnostics and allow external tooling to react to specific error conditions.
