Subject: [PATCH] fix: switch to wpa_supplicant backend for standard WiFi
 support

- Change NetworkManager backend from iwd to wpa_supplicant
- Remove custom WiFi profiles to allow auto-detection
- Remove iwd service and package
- Add standard WiFi packages: wpa_supplicant, wirelesstools, iw
- This provides standard NixOS live ISO WiFi functionality

Fixes WiFi controller detection issues in live USB environment.
