fix: provisioner now extracts archives and discovers disks before conversion

Browse source 
The job submission receives the original filename (e.g. Debian_13_VMG.7z)
but qemu-img convert needs the actual VMDK path inside the archive.
Now reuse extract_if_needed() + discover_disk() from converter module
to locate the real disk image before conversion.
