Add test coverage for _map_nm_wifi method

[Copilot]

Addresses #5184 by adding comprehensive test coverage for the Interface._map_nm_wifi static method, which maps NetworkManager wireless interface data to internal WifiConfig objects.

Tests Added

Added 12 test cases covering:

• Early returns: Non-wireless interfaces, missing settings
• Authentication methods: OPEN, WEP, WPA-PSK, unsupported (wpa-eap)
• WiFi modes: infrastructure, mesh, adhoc, ap
• Signal strength: Present, absent, wireless object without active AP
• Edge cases: Missing wireless settings, missing mode (defaults to infrastructure)

Implementation

All tests use mocking to avoid NetworkManager D-Bus dependencies:

def test_map_nm_wifi_wpa_psk_authentication():
    """Test _map_nm_wifi with WPA-PSK authentication."""
    mock_interface = Mock()
    mock_interface.type = DeviceType.WIRELESS
    mock_interface.settings = Mock()
    mock_interface.settings.wireless_security = Mock()
    mock_interface.settings.wireless_security.key_mgmt = "wpa-psk"
    mock_interface.settings.wireless_security.psk = "SecretPassword123"
    # ... additional setup ...
    
    result = Interface._map_nm_wifi(mock_interface)
    
    assert result.auth == AuthMethod.WPA_PSK
    assert result.psk == "SecretPassword123"

Tests follow existing patterns in test_configuration.py and validate all code paths including the warning path for unsupported authentication methods.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• esm.ubuntu.com
  • Triggering command: /usr/lib/apt/methods/https (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
