fix: wait for Proxmox resize task before VM start (v1.2.0)

- configure_vm: capture resize UPID and call wait_for_task(120s)
  before returning; prevents lock conflict when VM is started right
  after disk resize
- resize_vm_disk / resize_container_disk (x2): same fix applied
- remove unnecessary restart_vm() after manual QEMU disk resize —
  resize is a storage-layer operation and does not require a reboot;
  the auto-restart was causing a second lock conflict

Fixes: can't lock file '/var/lock/qemu-server/lock-xxx.conf' - got timeout
Fixes: command '/usr/bin/qemu-img resize' failed: got timeout
