Rdzleo f9dc7d4861 feat: 触屏版迁移到按键版，两键实现全部交互功能

1. 按键驱动重构：GPIO中断+手动去抖 → iot_button组件（单击/双击/长按）
2. 新增key_nav按键导航管理器：上下文状态机 + Set界面焦点蓝色边框高亮
3. 移除所有触摸手势/点击事件（ScreenHome/ScreenImg/ScreenSet）
4. 应援灯颜色切换优化：DISPOFF→直接写GRAM→DISPON，消除分band刷新
5. 亮度调节按键化：BOOT +10% / KEY -10% / KEY长按退出
6. 休眠管理适配：按键唤醒统一由key_nav处理
7. 新增迁移总结文档 docs/touch-to-button-migration.md

Creation of an unlimited number of buttons, accommodating various types simultaneously.
Multiple callback functions for a single event.
Allowing customization of the consecutive key press count to any desired number.
Facilitating the setup of callbacks for any specified long-press duration.
Support power save mode (Only for gpio button)
