    wifi-scripts: only enable RSN override when parameters differ
    
    When encryption is set to 'sae' without explicit pairwise cipher in
    non-HE/EHT mode, both the main RSNE and override RSNE would advertise
    identical parameters (SAE+CCMP+MFP=2), adding unnecessary overhead.
    
    Check that the pairwise ciphers differ before enabling override. This
    preserves the intended behavior for HE/EHT modes (GCMP-256+CCMP vs CCMP)
    while avoiding pointless override IEs.
