3.24_433_TX版本：项目去UI化，删除OLED/菜单/按键，TX已验证，RX待验证

删除内容：
- 删除OLED显示相关代码（u8g2库、I2C接口）
- 删除按键输入相关代码（key.c）
- 删除菜单系统（MultMenu整个目录）
- 删除USB CDC功能（USB_DEVICE目录）
- 删除旧的E32演示代码（e32_demo.c/h）
保留内容：
- Driver_RF433核心驱动（已封装完整）
- rf433_tx_app.c（TX应用层，独立无UI依赖）
- rf433_rx_app.c（RX应用层，独立无UI依赖）
- GPIO LED指示功能（LED_TX/LED_RX）
