Improve WiFi quick scan error handling and Linux tool fallback

Browse Source 
- Add fallback mechanism to try multiple tools (nmcli -> iw -> iwlist)
- Improve error messages for iw/iwlist with root privilege detection
- Enhance nmcli scanner to try without interface if specific scan fails
- Better error reporting in frontend showing actual backend errors
- Add logging throughout scan process for debugging

This fixes quick scan immediately failing on Linux systems by trying
multiple tools and providing meaningful error messages.
