Streamline WiFi scanning with auto monitor mode and better device detection

Browse Source 
- Auto-enable monitor mode when clicking Start Scanning (no manual step needed)
- Improved WiFi interface detection using airmon-ng for chipset info
- Added lsusb fallback for USB adapter identification
- Fixed interface display format in enableMonitorMode callback
- Better error handling and status notifications during scan startup
