Refactor detect_icon_color_mode to accept attribute path suffix

•	Removed bpy.context.preferences.themes[0] from the input and hardcoded it in the function.
	•	color_path now only requires the attribute path suffix (e.g., "user_interface.wcol_regular.text").
	•	Updated error handling to default to "dm" instead of "lm".
