refactor: 全面优化Jenkinsfile

修复的问题：
1. 修复所有序列化问题（使用@NonCPS注解和switch语句）
2. 移除未使用的函数（buildAndPush, deployService, getContainerName）
3. 实现真正的并行构建（Build Services阶段）
4. 优化健康检查（可配置超时和间隔）
5. 提取硬编码值到环境变量
6. 改进代码组织和可读性

性能改进：
- 并行构建服务（预计节省40%构建时间）
- 优化健康检查间隔（从10秒降到5秒）
- 并行最终健康检查

代码质量：
- 使用@NonCPS避免序列化问题
- 使用switch替代Map查找
- 统一函数命名规范
- 添加详细注释

从417行优化到~380行，提升可维护性和性能。
