Use get_style_qss and update qdarkstyle deps 
Load the GUI stylesheet via get_style_qss (from gui_assets) instead of reading BASE_DIR/style.qss, and switch qdarkstyle to the PySide6 loader. Also adjust pyproject.toml to declare qdarkstyle for non-Linux x86_64 platforms and pin qdarkstyle==3.1 only for Linux x86_64 (matching the conditional pyside6 pin). This centralizes style handling in gui_assets and aligns the qdarkstyle loader and dependency constraints with PySide6 usage.
