refactor(core): 重构配置与入口模块，统一配置结构并调整导入

- 扁平化应用配置类，合并数据库、LLM、爬虫和通知配置
- 重新实现配置加载，统一环境变量前缀和字段命名
- 入口脚本调整，增加源码路径处理，支持模块绝对导入和直接运行
- HRAgentApplication中使用新配置字段访问方式
- 优化通知渠道注册逻辑，适配新的配置字段重命名
- 模块路径统一由ylhp_hr_2.0改为ylhp_hr_2_0，确保导入一致性
- 删除旧配置模块，避免配置重复和混淆
- service.analysis包暴露MockLLMClient，完善LLM客户端选项
- 保留主入口运行示例，演示系统初始化与功能打印
