[GUI] Localhost logging message

[befl3]

Starting the gui states that a unicorn is running on 127.0.0.1:8000
However, the gui can only be fully accessed via localhost:8000 or localhost:8000/gui

• We might fix this (so the gui works with both 127.0.0.1 and localhost)

and/or

• we might filter the uvicorn debug messages and replace them with our own messages. We should still provide information such as "dynamic layer is being updated" but maybe with our own logging.
