feat: 新增多个电力集团采购平台爬虫

- 新增4个电力集团采购平台爬虫：
  * 中国大唐集团电子商务平台 (CdtCrawler)
  * 大连能源采购平台 (CeicCrawler)
  * 华润守正采购交易平台 (SzecpCrawler)
- 更新 BidCrawlerService，集成新的爬虫到爬虫任务中
- 添加环境变量示例文件 .env.example，包含数据库和代理配置
- 优化 .env 文件，添加代理配置示例
- 为所有新爬虫添加完整的单元测试文件
- 使用与现有爬虫相同的反检测策略（人类行为模拟）
- 支持分页抓取，每个平台最多抓取5页数据
- 统一的错误处理机制，单个爬虫失败不影响其他爬虫执行
