refactor(nav): use exit code 75 to suppress redundant "Press Enter" prompt

- app submenus return 75 on back/exit instead of 0
- index menus capture child exit code and skip pause when rc is 75
- applies to apps (coolify, pterodactyl, uptime-kuma, cloudpanel, proxmox) and tools (server-benchmark, system-infos) indexes
