refactor: extract interactive menus into dedicated index scripts

- move apps menu from inline lxs.sh function to apps/index.sh
- add tools/index.sh as entry point for tools menu
- rename system-tools.sh to system-infos.sh
- simplify help text to point users to the interactive menu
- update README directory tree to reflect new structure
