Improve Bluetooth adapter reset with multiple fallback methods

Browse Source 
- Check if running as root, try sudo -n if not
- Try rfkill unblock bluetooth first
- Fall back to bluetoothctl power off/on if hciconfig fails
- Better error messaging when adapter stays down
- Suggest manual command when auto-reset fails
