feat: rename GameState to SessionState for consistency

- Rename enum GameState to SessionState in typing_screen.rs
- Update all 40+ references across typing_screen.rs and stage_manager.rs
- Update import statement in stage_manager.rs
- Maintain all existing functionality while improving semantic consistency

This aligns with the session-based terminology established throughout the codebase.
