fix(deploy): apply VM config reliably after clone

- wait for clone lock release before config.put (cross-node clones kept
  lock past wait_for_task, dropping ALL requested settings silently)
- configure_vm applies params in independent groups (compute/network/
  cloudinit/disk) with per-group errors and lock retry
- set sockets=1 with cores so total vCPU matches request
- keep template net0 model/MAC/options, replace only bridge
- disk resize: pick boot disk via regex over all buses, report failures
- surface config errors as deploy warnings in UI toast instead of
  silent success
