List VMs and LXC containers from the current cv4pve-cli context and
start, shutdown, stop and reboot them, change cores and memory, and
grow disks. The app shells out to `cv4pve-cli -o json` and stores no
credentials.
- Every mutating call uses --wait: without it cv4pve-cli exits 0 even
when the task fails.
- shutdown, stop and reboot need confirmation; disk growth is
increment-only and asks again because it cannot be undone.
- After an action the acted-on guest's status is read from
status/current, because /cluster/resources lags a few seconds.
- Notifies when a cores/memory change is pending until reboot.
Tests mock cv4pve-cli (85 tests). Live-tested edit, shutdown, start
and reboot on CT 104 (mainframe), restored afterwards; disk resize
was not run live.
