feat: 添加一键共享所有打印机功能
新增 share_all_printers() 函数和菜单选项6，实现： - 检查 CUPS 服务状态 - 显示所有打印机当前共享状态 - 执行 cupsctl --share-printers 启用全局共享 - 对每台打印机执行 lpadmin -p <name> -o printer-is-shared=true - 重启 CUPS 和 Avahi 服务 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
