refactor: Centralize resource path management

Create a new `settings.py` file to define and manage global application paths.

Modify UI components (`split_view_widget.py`, `view_settings_dialog.py`) to use the centralized `ICONS_DIR` path constant instead of hardcoded relative paths for icons. This improves maintainability and makes the application independent of the working directory.
