Fix TSCM WiFi detection, SDR capabilities, layout, and correlation/cluster emission

- Use networksetup instead of deprecated airport utility for macOS WiFi detection
- Fix SDRDevice attribute access (use getattr instead of dict .get())
- Move Detected Threats panel next to RF Signals in 2-column grid
- Always run correlation/identity analysis at sweep end, even if stopped by user
