ADAX Local Bluetooth setup fails when SSID contains special characters (e.g., space)

The problem

I encountered a repeatable issue when setting up the ADAX Local integration in Home Assistant using Bluetooth. The setup fails with the following error in the logs:

Traceback (most recent call last):
  File "src/dbus_fast/message_bus.py", line 797, in dbus_fast.message_bus.BaseMessageBus._process_message
  File "/usr/local/lib/python3.13/site-packages/bleak/backends/bluezdbus/manager.py", line 1087, in _parse_msg
    watcher.on_characteristic_value_changed(

    )
    ^
  File "/usr/local/lib/python3.13/site-packages/bleak/backends/bluezdbus/client.py", line 188, in on_value_changed

  File "/usr/local/lib/python3.13/site-packages/adax_local/__init__.py", line 121, in notification_handler
    raise InvalidWifiCred
adax_local.InvalidWifiCred

After troubleshooting, I found that the cause was my Wi-Fi SSID containing a space ("My Home 2.4GHz"). When I renamed it to "MyHome24" (no space or special characters), the pairing and Wi-Fi configuration completed successfully.

It appears that the ADAX Bluetooth provisioning process fails when the SSID contains special characters such as spaces, dots, or symbols. This could be related to how the credentials are serialized before being sent to the heater.

It might help to sanitize or quote the SSID and password before transmission to avoid this error.

Or, at least, inform about this in the setup process.
