refactor(debug): 重构调试日志环形缓冲区管理

- 将日志环形缓冲区从静态数组改为动态堆分配
- 实现启动时大容量缓冲区和运行时小容量缓冲区的切换机制
- 添加日志环满时优先保留错误和警告信息的清理策略
- 优化内存使用，在日志为空时避免不必要的内存分配
- 移除调试日志中的冗余字段显示

feat(api): 更新CAN接口为批量发送模式

- 将 `/can/send` 接口替换为 `/can/send_batch`，支持1到N帧的批量发送
- 更新API文档中的接口描述和使用示例
- 修改请求参数格式为 `{"ch":0,"frames":[{...}]}` 返回格式为 `{"status":"ok","results":[...]}`
- 单帧发送也需要通过send_batch接口实现

feat(monitor): 新增GD32 ADC调试反馈处理功能

- 添加gd32_adc_feedback组件用于解析0xC4类型的SPI反馈
- 实现ADC数据解析包括温度、电压等参数的计算和转换
- 在can_feedback_task中集成ADC反馈分发逻辑
- 添加线程安全的数据获取和年龄检查接口

refactor(config): 优化任务栈大小配置并调整OTA块大小

- 重新评估各任务栈使用情况，优化HTTP、WiFi、SPI等工作任务的栈大小
- 将HTTP服务器栈从8KB调整至7KB，WiFi OTA任务栈从4KB调整至3KB
- OTA块大小从2KB调整回4KB以提升传输吞吐性能
- 重新整理配置文件结构，移动WiFi模式配置位置
