Add unified WiFi scanning module with dual-mode architecture

Backend:
- New utils/wifi/ package with models, scanner, parsers, channel analyzer
- Quick Scan mode using system tools (nmcli, iw, iwlist, airport)
- Deep Scan mode using airodump-ng with monitor mode
- Hidden SSID correlation engine
- Channel utilization analysis with recommendations
- v2 API endpoints at /wifi/v2/* with SSE streaming
- TSCM integration updated to use new scanner (backwards compatible)

Frontend:
- WiFi mode controller (wifi.js) with dual-mode support
- Channel utilization chart component (channel-chart.js)
- Updated wifi.html template with scan mode tabs and export
