Improved upgrade reliability

Upgrades are now more reliable when mods are incompatible with the installed Proxmox version or when files have been modified by other tools.

Incompatible mods will no longer unnecessarily block PVE-mods upgrades. They will be automatically retried after updates and re-enabled when compatibility is restored.

Improved warnings and recovery guidance also make it easier to identify and fix mod-related issues.
