Add environment variables to quickshell wrapper

- Add ILLOGICAL_IMPULSE_VIRTUAL_ENV for Python virtual environment
- Add XDG_DATA_DIRS with gsettings-desktop-schemas for GNOME schemas
- Add LD_LIBRARY_PATH with all required system libraries
- This ensures Light mode selection works in quickshell settings

Fixes the issue where Light mode button was unresponsive due to missing
environment variables and library paths in the quickshell wrapper.
