Add Confirmation Prompt for Shutdown/ Pause/ Reboot VM Actions in Web Console on RHOCP 4.

Issue

• The shutdown, restart, and pause buttons for virtual machines are currently located very close to the action menu in the web console, increasing the risk of accidental clicks. In contrast, other hypervisor platforms typically include a confirmation step before executing such critical actions. Implementing a similar confirmation prompt here would help prevent unintentional operations and enhance user experience.
