Inserted calls to user_model->validate_session() in all controller constructors to ensure user sessions are validated before authorization checks. This improves session handling and security across the application.
As per request of some users, sometimes new modes or missing modes had to be
added into the code.
As that hardcoded lists are not eary maintainable, we created a new table with
all modes and submodes listed and make this list editable.
Now one can activate or deativate modes from beeing shown within the select-
list in QSO Window.
