✨ feat(adc): 重构ADC数据处理架构，引入1ms定时器中断处理

Browse Source 
- 新增TIM2定时器配置，用于1ms周期的ADC数据处理中断
- 将主循环中的ADC数据处理逻辑移至定时器中断回调函数中
- 新增ProcessAdcData函数，封装完整的ADC数据处理流程
- 优化数据缓冲区大小，从2增加到64，提升数据处理能力
- 调整DMA中断优先级，优化系统实时性

🔧 chore(config): 更新STM32CubeMX项目配置

- 在IOC配置文件中添加TIM2定时器配置
- 更新NVIC中断优先级配置
- 调整DMA中断优先级设置
- 更新项目初始化函数调用顺序

📦 build(storage): 优化数据存储缓冲区配置

- 将数据存储缓冲区大小从1024字节增加到32768字节
- 提升数据写入效率，减少文件系统操作频率
