Fix: Possible online backup crashes VMs on QEMU < 9.1 (7250b75)
A bug in the backup cleanup process could cause the VM's QEMU process to terminate unexpectedly during an online backup (CVE-2024-7409). This affected all QEMU versions up to 9.1 and required a manual VM restart.

Fix: Offline backups no longer hang before failing (4b562f7)
Offline backups would hang for 120 seconds then fail with a timeout error. An internal connection was not being released properly, preventing the backup from proceeding.

Fix: Offline backup progress now reports correctly (f4d7754, f4a2309)
Offline backups previously showed 0% progress throughout the entire operation. Progress now updates in near real-time.

Fix: Incorrect hypervisor license count calculation (a83f1d2)
Hypervisor count was being calculated incorrectly, which could cause license validation to fail or report inaccurate usage.
