fix: Auto-update system tray menu when spaces change

- Remove dead_code attribute from update_tray_spaces function
- Add AppHandle parameter to create_space and delete_space commands
- Call update_tray_spaces after space creation, deletion, and activation
- Add refresh_tray_menu command for manual tray refresh

The system tray now automatically reflects:  - New spaces when created  - Space removal when deleted  - Active space indicator when switching spaces

Fixes issue where creating a new space didn't appear in system tray.
