Add DHCP leases management to dashboard and UI

Browse Source 
Implement a new API endpoint to retrieve current DHCP leases from dnsmasq, enhancing the dashboard's functionality for monitoring network devices. Update the home.html template to display DHCP lease information in a structured table format, including IP, MAC, hostname, and expiry details. Introduce buttons for enabling and disabling DHCP network boot, improving user interaction. Enhance JavaScript to fetch and display lease data dynamically, ensuring users have real-time visibility of network activity.
