[BUG] WiFi Changes do not work on Raspberry Pi

[Tekunalogy]

Describe the bug

The following command used by DWE_OS for WiFi manager, fails in the Raspberry Pi OS.

nmcli --terse --fields active,ssid,bssid,mode,chan,freq,signal,security,wpa-flags,rsn-flags device wifi list

Network Manager is not running on RPi since RPi uses the older dhcpcd by default.

To Reproduce

Steps to reproduce the behavior:

• Install Instructions followed here

Expected behavior

DWE_OS should run on the host IP on port 5000.
