feat(notification): 增加钉钉发送图片和文件功能，支持OSS图片上传
- 在DingTalkBot中添加发送图片消息（自动压缩）功能，支持大小限制自动处理 - 添加发送图文混合消息、发送文件消息接口，优化钉钉通知能力 - 实现发送本地图片链接和通过OSS上传图片再发送Markdown图文两种机制 - 新增阿里云OSS上传工具模块，支持文件和图片上传及预签名URL生成 - 创建每日任务调度脚本，实现每日交易日检查、策略执行、结果上传并通知 - 调整回测策略开始日期至2022年，适配最新数据范围

|
||||
|
||||
功能：
|
||||
1. 每天15:00收盘后检查是否为交易日
|
||||
2. 如果是交易日，执行策略回测
|
||||
3. 上传报告图表到OSS
|
||||
4. 发送结果到钉钉
|
||||
|
||||
用法：
|
||||
python scripts/daily_scheduler.py
|
