Two changes to prevent duplicates in Settings > Virtual Environment:
1. Install script: only clear Proxmox state files on fresh installs,
not upgrades. Previously every install forced re-registration.
2. Auto-register dedup: match agent re-registrations by server name
when both the existing entry and new request have Pulse-created
tokens (pulse-monitor@pam!pulse-*). This catches the case where
the agent creates a new token after state files are cleared.
