Set the default generic_mode to True in the config manager and update GUI initialization to distinguish between a missing config and an explicit False. Replace usages of `ConfigManager.get(... ) or False` with a None check so that an explicit False value is respected. Changes made in ytsage/utils/ytsage_config_manager.py and GUI initializers in ytsage/gui/ytsage_gui_main.py and ytsage/gui/ytsage_gui_dialogs/ytsage_dialogs_settings.py.
