Add support for SAE Wifi Auth Type (and maybe catch the ValueError)

[Alphare]

Hi, thanks for the very useful piece of software.

I just got a new router and it uses newer SAE (WPA3) authentication, which is not listed in your enum.

Traceback (most recent call last):
  File "/app/share/cobang/cobang/pages/scanner.py", line 707, in display_result
    if wifi := parse_wifi_message(raw_data):
               ~~~~~~~~~~~~~~~~~~^^^^^^^^^^
  File "/app/share/cobang/cobang/messages.py", line 80, in parse_wifi_message
    winfo.auth_type = WifiAuthType(auth_type) if auth_type != 'nopass' else None
                      ~~~~~~~~~~~~^^^^^^^^^^^
  File "/usr/lib/python3.13/enum.py", line 726, in __call__
    return cls.__new__(cls, value)
           ~~~~~~~~~~~^^^^^^^^^^^^
  File "/usr/lib/python3.13/enum.py", line 1203, in __new__
    raise ve_exc
ValueError: 'SAE' is not a valid WifiAuthType

I think this requires two fixes: catching the ValueError and adding support for SAE.
