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.

The TFTP root contains e.g. `start4cd.elf`, `fixup4cd.dat`, `config.txt`, `cmdline.txt`, `kernel8.img`, and other boot files. For a custom kernel or initramfs (e.g. for provisioning), add or replace files in `/srv/tftpboot` and adjust `config.txt` / `cmdline.txt` as needed.
## DHCP leases
On the LXC, dnsmasq stores DHCP leases in **`/var/lib/misc/dnsmasq.leases`** (Debian/Ubuntu default). To see which devices got an IP on the provisioning LAN:
```bash
# On the LXC (or via SSH)
cat /var/lib/misc/dnsmasq.leases
```
Each line is: *expiry_epoch MAC IP hostname client_id*. Example: `1734567890 aa:bb:cc:dd:ee:ff 10.20.50.101 reterminal 01:aa:bb:cc:dd:ee:ff`
