✨ feat(main): 新增usb连接状态检测与自动文件系统管理功能

Browse Source 
- 新增usb连接状态检测函数，根据usb连接状态自动切换数据采集模式
- 新增文件系统动态挂载/卸载功能，usb连接时卸载文件系统，断开时重新挂载
- 修改系统启动逻辑，根据初始usb连接状态决定是否开始数据采集
- 新增usb模式系统状态，完善系统状态机

🐛 fix(sdio): 修复sdio配置问题并启用中断

- 修改sdio时钟分频为2，优化sd nand通信时序
- 启用sdio数据线内部上拉电阻，提高信号稳定性
- 提高sdio dma传输优先级至最高，确保数据传输实时性
- 启用sdio全局中断并设置优先级为9

🔧 chore(config): 优化系统配置参数

- 修改系统滴答定时器中断优先级为0（最高优先级）
- 增加堆栈大小至0x1000，增加堆大小至0x800
- 修改usb msc媒体数据包大小至32768，提高usb传输效率
- 修改fatfs配置，设置最大最小扇区大小为512字节

♻️ refactor(usb): 重构usb存储接口实现

- 修改usb存储初始化逻辑，避免重复初始化sd卡
- 优化usb存储容量报告机制，强制报告512字节扇区
- 增加sd nand读写超时等待机制，确保数据传输完成
- 修改usb中断优先级为11，避免与sdio中断冲突

📝 docs(headers): 更新头文件声明

- 在stm32f4xx_it.h中添加sdio中断处理函数声明
- 在system_monitor.h中添加usb模式系统状态定义
- 更新data_storage.h中的数据存储路径配置
