Stop spinner on cleanup & simplify qm set

Call stop_spinner in cleanup() to ensure any active spinner is stopped on exit. Consolidate duplicated qm set branches in ubuntu2604-vm.sh into a single invocation to reduce code duplication and simplify VM disk/serial configuration. Remove the explicit ide2 cloudinit device and redundant cloud-init status messages; setup_cloud_init() is still invoked when USE_CLOUD_INIT is enabled, keeping cloud-init configuration centralized.
