refactor: 移除executeTemplateByCode接口的后端图片审核功能

- 简化执行流程，直接执行模板跳过后端审核
- 支持前端传递auditTaskId参数用于审核追踪
- 移除UnifiedContentService依赖和相关审核逻辑
- 删除handleAuditComplete和startTemplateExecution方法
- 更新API文档说明前端审核职责
- 修改测试用例适配新的执行流程
- 保持数据库字段兼容性，auditTaskId改为前端传入

变更影响：
- executeTemplateByCode接口不再执行后端图片审核
- 执行记录状态直接设为PROCESSING
- 前端需要在调用接口前完成图片审核
