Smart-flower-system/components/ui/screens.c
Wang Beihong bec31c01ce 在主应用中更新显示驱动和 MQTT 主题 
- 将显示驱动从 lvgl_st7735s_use 改为 lvgl_st7789_use，在 CMakeLists.txt 和 main.c 中。
- 将 MQTT 警报主题从“topic/alert/esp32_iothome_001”更新为“topic/alert/esp32_iothome_002”。
- 重构 UI 任务，去除周期性屏幕切换逻辑，专注于界面刷新。
- 调整错误处理，使新的显示驱动程序用于错误信息。
