Refactor dashboard to remove network boot support and update related UI elements</message>

<message>Eliminate network boot options from the dashboard, including API endpoints and UI elements, to streamline the provisioning process for USB boot only. Update messages and documentation to reflect the removal of network boot functionality, ensuring clarity for users. Adjust the cloud-init build process and related templates to focus solely on USB boot mode, enhancing the overall user experience and simplifying the workflow.
