Add status tracking for network boot actions in dashboard

Implement a new function to write status updates during device deployment and backup actions, enhancing user feedback. Update the API to call this function with appropriate messages based on the action taken. Modify the network boot toggle script to improve clarity and functionality, ensuring proper management of DHCP options. Update permissions for the toggle script to ensure it is executable. Additionally, update the initrd.img to reflect recent changes in the network boot process.
